Terahertz Scanners See Inside Sealed Packages
opticsorg writes "Japanese scientists have demonstrated a system that detects the presence of illicit drugs that are concealed within an envelope. Tests to date have shown that the imaging system can successfully detect and identify a range of substances including ecstasy (MDMA) and methamphetamine. The researchers are now working with companies to develop a mail screening system that could suit use in post offices and airports."
Bad scientist, bad, bad scientist! Go cure cancer or something useful!
Strange women lying in ponds distributing swords is no basis for a system of government.
Like any self respecting dealer would ship product through the USPS.
... because you know that every drug dealer makes his/her shipments for $0.37 through the United States Postal Service, saving thousands and thousands of dollars a year on trunk repair and gasoline charges ...

Someone figures out how to reflect these waves to give off false or misleading information... And since the intent seems to be to keep peoples rights intact, you cant just open the package. This will only last as a viable anti drug solution until three MIT stoners get bored.
I have a Cig, but do you have a light?
Just make sure you wrap all your drugs in aluminum foil. Not only should it reflect those nasty little scans. Should cause quite the ill effects on their scanner.
Technology, the cause of and solution to all of life's problems.

"At the heart of the Japanese system is a compact and tunable optical parametric oscillator (OPO) that emits terahertz waves. The OPO is made from a nonlinear crystal (MgO:LiNbO3) that is pumped by a Q-switched Nd:YAG laser. It emits terahertz radiation that is tunable between 1 and 2.5 THz.
Terahertz waves of several different frequencies are scanned over the envelope and the transmitted radiation is picked up by a pyroelectric bolometer and analyzed by a computer."
Someone seems to have messed up and posted a garbled version of the page. Can someone please post the English version?

Yep, you're right. Back in High School (~1989) I drove home really stoned one night at 2am over roads with 50MPH speed limits, and the next day, the person who was the passenger in the car told me that I was going about 20 miles per hour. Yessiree Bob, I sure felt safe then realizing that I had no fucking clue that I had even been driving the night before. Nothing at all reckless about that.
