Terahertz Imagery Progresses
ke4roh writes "Since Slashdot last discussed
terahertz imaging, the European Space Agency's Star Tiger project has
taken terahertz images of a human hand.
Some of the pictures
show just how useful the imagery might be for peering through walls and such - one of the images is through a 15mm pad of paper." The EE Times has another story.

i saw a story line similar to this on the show ALIAS. They had this deally on a satellite or something in space. They used it to view beneath chunks of ice in the artic. cool beans
hope they took pictures of some good looking hands, i mean, one without warts and stuff. I need new images for my hand fetish website!
I just heard some sad news on talk radio - Horror/Sci Fi writer Stephen King was found dead in his Maine home this morning. There weren't any more details. I'm sure everyone in the Slashdot community will miss him - even if you didn't enjoy his work, there's no denying his contributions to popular culture. Truly an American icon.

Snip of some info from the tiger page:
Terahertz imaging can be achieved by observing the natural terahertz waves emitted by pretty much everything. Unlike light, terahertz waves are able to propagate through cloud and smoke providing a powerful advantage for certain remote sensing measurements. From a practical aspect they are also able to pass through windows, paper, clothing and in certain instances even walls.
Sounds like thermal imaging on steroids. Eventually, would this become the standard military surveillance method that could be used on a UAV in enemy or (god forbid) domestic airspace?

According to the article, the frequencies are used only certain moths. It also talks about using the frequency to carry terabit wireless networks...
Does this mean that that I could use the wireless network to create swarm of attack moths that can see through reams of paper.

These are in no particular order. Just spewed into this document from my head.....
What I percieve is wrong with my life (what I would change if I could):
- Can't party when I want to (drinking, loud music, hanging out with friends, etc.)
- Can't play on my computers when I want to, and feeling guilty when I do
- I have little to no control over what happens in the day-to-day events in my life
- Can't understand why people make simple, stupid mistakes (leaving cabinet doors open, being unable to drive, etc.)
- Coming home from work every day to a noisy, messy home
- Despite devoting the better part of my life to work, I never have the money to buy the things that make me happy
- My daily week life consisting of:
- Work
- A 3 hour evening consisting of noise and mess
- Sleep
- My weekend life consisting of:
- Lounging for 2 hours in the morning
- Some combination of the following three things:
- Watch the kids while my wife goes outside and works
- Go outside to work
- Take a pointless drive to some shopping center to look at things we can't afford, or to buy
groceries, etc.
- A three hour evening consisting of noise and mess
- Sleep
- Sleeping in the spare bedroom because my kids and wife are hogging all the room in my bed
- Having to compromise my home's asthetics because I have kids (ie, safety gates all
over the house, beds lowered to the floor, being unable to sleep in my own bed, etc.)
- Driving a piece of junk vehicle daily, and when it finally dies only being able to *marginally* afford
another piece of junk vehicle
- I don't get paid enough at work for the knowledge that I have
What I am doing wrong in my life:
- Not spending time with my family
- Not appreciating what hard work it is for my wife to stay home with the kids during the day
- Planning to spend money frivolously
- Getting angry at a three year old because she's made a mess or angry at a 10 month old because she's crying and
won't stop until I get up and walk around with her
- Holding a grudge against my kids because they don't allow me to keep an asthetically pleasing home
Goals for therapy:
- Be a happy person in my day to day life
- The abliity to turn lemons into lemonade, as the saying goes, rather than dwelling on bad situations
Random thoughts:
- Not really sure if my relationship with my wife is going to work long-term. I keep fantasizing about other women...
- I typically have trouble focusing in on things; lots of "clutter" when I try to concentrate (song stuck in head, etc.)
- I always feel as if everything in my life is temporary and that I'm heading towards a final idealized goal of being
able to do anything that I like to do because I'll be wealthy, in shape, in charge, and with nothing to hinder me
- I'm constantly unhappy
- I rarely follow through on any project, either personal or professional, that I start out on
- I think about how relaxing it would be to just let go of all responsibilities
- Sometimes I think that death wouldn't be such a bad thing. NOT THAT I WOULD HARM MYSELF, but if it happened that
maybe my wife and the kids would be better off, and I'd be done with whatever it is that I'm supposed to be doing
I just know that some Linux coder out there is thinking, "Hmm, so if I see thru everything, what the hell do I actually end up seeing anyway?!"

Just thinking back to movies of X-Rays being used to show pictures of your foot, to see how it fit inside a new shoe. Sure, at the time it was a great selling gadget, but I wonder how much damage it did to the people who used it, and those who worked in the store with it. I'm thinking also of modern x-ray technicians, who wear special lead-lined vests, and limit the exposure as much as possible.

A new area of remote sensing and communication is opening up, thanks to groundbreaking technology from the European Space Agency.
StarTiger, a European Space Agency project, has taken the first terahertz picture of a human hand. Terahertz radiation lies on the boundary between radio and light waves and is far more difficult to detect and analyse than either, but is of huge interest for medical, security, environmental and communication uses; the technology could, for instance, theoretically carry wireless data at terabit speeds.
ESA originally investigated the radiation for sensing atmospheric and ground phenomena from satellites, but it is now examining terrestrial applications of the new frequencies. "We have recognised the huge potential in non-space applications, and in parallel to exploiting the use of terahertz waves and the StarTiger technology in space, we have kicked-off a commercialisation study to identify the best way of transferring it into terrestrial systems," said Pierre Brisson, head of ESA's Technology Transfer and Promotion Office.
One terahertz is 1,000 gigahertz, and most current radio technology stops at around 100 GHz: 0.1THz. Everything gives off terahertz radiation naturally, and like radio waves -- but unlike heat or light -- the waves can pass through some solid objects. Like light, it is possible to focus the radiation and create images as if the intervening material were translucent, and by analysing the frequencies given off the chemical and physical characteristics of the object can be worked out.
Terahertz radiation has wavelengths too short for normal radio antennae to pick up but too long for normal optical techniques and thus the band has been closed to experimenters and scientists. Until now, the only known user of the frequencies has been a species of moth. By using nano-engineering techniques to create micro-machined arrays of minute antennae, the StarTiger team has created a sensor array that can image objects at 0.2THz and 0.3THz.
"The final version was an enhanced imaging system incorporating a two-colour 16-pixel detector array of the size of a postage stamp. This advanced system incorporated revolutionary silicon micro-electrical-mechanical systems (MEMs) technology," said Chris Mann, the project manager at Rutherford Appleton Laboratories (RAL) in Oxfordshire, where most of the work has been done. "The enhanced system delivered images that confirmed the nature of terahertz waves. An imager can show details of features under the skin, confirming the potential of this technique." As well as images of a hand taken through 15mm of paper, the project has also released pictures of the human body imaged through clothing.
Because the field is so new and unexplored, many applications are still to be tested. Detecting explosives or biological agents in parcels, cancers beneath the skin, the state of wounds beneath dressings, and seeing through fog: all have been suggested by StarTiger and other researchers.
Today scientists have announced a new way to get more pornography online by using new technology.. I could see where this would be useful for X-rays and such iof it could get cleaner. it is kind of cool however. I just dont want to see this kind of technology coruppted. (By the way, i have no problems with porn, i like it just as much as the next guy. =) )
---
The picture of the hand, at least, was taken using just the rays the hand emits naturally.
A device that can be used to see through walls has potential anti-terrorism uses, and if tweaked it could probably be used as a replacement for the mildly-dangerous xray technology. Also being able to be used for communications, this is a step in the right direction for research into radio technologys.
Imagine the X10 camera ads this will bring forth...

Light waves can't pass through solid objects? Except, you know, glass. Or clear plastic. Visible light can't pass through things that are opaque, moron. That's why they invented the damn word in the first place.

And from what I understand from the article, TeraHertz radiation is something that objects emmit naturally. So I'd assume devices using this technique would not be exposing you to radiation, as X-rays do.
Security checkpoints might adopt this also. Airports currently use x-rays which can be damaging to high speed film and has other negative issues also. The article mentioned that certain chemical characteristics could also be gleaned from an imaging system such as this, since the object itself (and the chemicals it contains) is the thing emmitting the radiation. Possibilities include detecting explosives and drugs.
Also, just as a side note, the pictures of a human body through clothing referred to in the article are of some fat guy with flabby tits. View at your own risk.
MacGyver built a teraherz camera out of a banana peel and a rubber band.

How feasible would it be to focus though multiple layers of different materials, or though one layer of unknown thickness (eg. snow from an avelanche) to look for people and/or things like shipwrecks?
If they can do that, and have it be portable, the military would likely be interested too. In either case, I can see scientific and medical applications for this.
Surprisingly, the Supreme Court ruled last year -- in an opinion written by Scalia (conservative) and joined by Souter (moderate) and Thomas (conservative), as well as Ginsburg and Breyer (both liberal) -- that the use of thermal imaging to detect marijuana grow lamps inside a house was illegal: It looks to me like terahertz imaging would fall under this ruling, and thus be illegal without a warrant. For now, anyway...

If this is so groundbreaking, why do they fail to mention that "terahertz radiation" also goes by another name: infrared? If it's so hard to detect and analyze, how come my $10 radio-shack universal remote control can do it?
The great-great-grandparent post is absolutely correct. The link displays some amazing photographs of the inside of the human body, which could only have been taken by terahertz imaging. I think you will all admit that you couldn't reproduce those photos by normal photographic means.
Wow. Those are impressive.
Tinfoil hats will soon be superceded by tinfoil longjohns and tinfoil wallpaper. Time to invest in aluminium futures I think.
Seriously though - this is too easy to beat for anyone who feels the need to.
Do these waves travel faster than 2.4 GHz waves? That would be news - I was under the impression that all waves traveled at the same speed.
Don't follow from work.
Finally, we can solve schroedinger's cat problem!
This smells suspiciously of renaming something old so it seems new.
In the early 1980s, the IRAS satellite did an all-sky survey at wavelengths up to 100 micron - i.e. about 3 THz.
The article says "most current radio technology stops at around 100 GHz." I myself have observed at 345GHz (0.345 THz) using radio astronomy techniques, and this was over 10 years ago. (This was at the Caltech Submillimeter Observatory, but it is not the only such observatory in the world.)
There is some new stuff here, however - at CSO, we had only one pixel, and they are talking about a compact 16 pixel detector (working at 0.2 to 0.3 THz - I.e. much the same frequencies as we were using.)
From an astronomical point of view, although detectors are a fairly big issue, our main problem was noise from the atmosphere - i.e. the atmosphere 'glows' at these wavelenghts, which tends to drown out the astronomical objects you are looking for.

A terabyte is a terabyte 2^40 in all circumstances.
Some HDD manufacturers say 10^12 but that is just so that they can pass off a 0.91 terabyte disc as a 1 terabyte disc.
1 kilobyte = 2^10 bytes
1 megabyte = 2^20 bytes
1 gigabyte = 2^30 bytes
1 terabyte = 2^40 bytes
There are words like kibibyte and all sorts of other stupid ideas. They were invented to confuse things. Even Micro$oft Windows seems to have this one right. I just looked at a PC running it. It said 38,050,996,224 bytes = 35.4 MB. If they can get it right, so can you!
When you get your terabyte disc, make sure you get 1,099,511,627,776 bytes. If you get just 10^12 bytes, they are stealing nearly 93MB of drive space from you!

There was a press release some time ago about the potential uses for this, and one of the major ones was for the fire service to enable them to see people in fires.
One of the more concerning things was that there was a somewhat odd camera-like device pointing out of their window straight towards my house for a significant amount of time a couple of years ago.. that somewhat disturbs me
Did anyone else look at their diagrams of the terahertz pixels? They were massive, stacked silicon structures. I can't imagine them getting the densities of those things anywhere near the densities of your run-of-the-mill digital camera anytime soon. It also explains the rather poor resolution of the sample images.
:)
Hopefully improvements will let them be rolled into low cost medical equipment (fairly) soon. Or cheap, light x-ray goggles, as everyone seems to want
Did the image get cut off, I wonder? or is one of the researchers missing a finger?

We'll finally be able to definitively state that yes, indeed, the cat is in the box.
Internet new is always like this. I mainly read cnn.com, and there are never pictures when there should be.
And another thing, they never link to sites when they talk about them. "New controversial web site does X" and there is no link.
please tell me what is so damn special about taking really fast photographs? I can see really fast (terahertz) cpus being cool, but photos that fast? Bah.
That is very cool. Nice work on the surface mapping.
That ruling established a new "brightline test" to determine if the technology can be used for surveillance. The ruling basically stated that if the technology is in common use, the police can go ahead and utilize it.
Shortly after that ruling, the federal government donated two thermal imagers to my local police department.
So, spying on people with teraherz imagers will only be unconstitutional until the technology is in common use.
take a few crappy pics of my hand, and say it was some terra-thingy, and I can get millions of hits on my webserver from slashdotters? yay!!

First, the metal detector alarm goes off like hell. Then you were invited into a dark room where you're striped for inspection of firearms.
From the article:
The whole point of engineering notation, in which you only express numbers in terms of powers of ten which are multiples of three, is that your number which gets multiplied is greater than one and less than 1,000, which would put you in the next bracket. It's Kilo Mega Giga Tera, for 10^3, 10^6, 10^9, and 10^12 respectively.
Hence .3 THz is not proper use of engineering notation, and thus it is not proper use of the name Tera. This is still Gigahertz range. When they get past .999(bar) THz and up to 1 THz, then this is terahertz imaging. This isn't even almost terahertz imaging, it's less than a third of the way there.
