CCD Image Sensor Inventors Win $500,000 Award
saskboy writes "CCD inventors were honoured this week. According to CBC News, "Willard Boyle, a Canadian scientist who helped invent the light-sensitive chip, accepted (the prestigious Charles Stark Draper Prize) in the U.S. on Tuesday. Boyle and George Smith will share the $500,000 US award for the invention of the "Charge-Coupled Device (CCD), a light-sensitive component at the heart of digital cameras and other widely used imaging technologies," the U.S. National Academy of Engineering said." Those other devices include the Hubble Space Telescope, and orthoscopic medical instruments. "Boyle and Smith came up with the idea for the device while working at Bell Laboratories in 1969. 'It was after maybe an hour's work,' Boyle recalled. 'We went over to the blackboard and we had some sketching there. We went down to our models lab and made one.'""
Or maybe you're not aware that light sensitivity was considered a peculiar and irritating characteristic of some semiconductor memory. Not much of a problem inside an opaque case, unless nuclear decay or cosmic rays generate a photon...
Take a jar and fill it with marbles. At some point, there just isn't any way to fit more marbles into the jar without breaking either some of the marbles or the jar itself. Consider that between each marble is a little space left over. All that space is wasted, even though you can't fit any more marbles into the jar!
Now empty the jar and fill it with bread. Once the jar is full, you can press down on the top of the bread and make more room. In fact, you can pretty much keep stuffing bread into the jar for quite a long time. Eventually you'll reach the saturation point and no new bread can be entered into the jar. However, the amount of bread in the jar is many times greater than the number of marbles which we just removed. There was less space between each piece of bread than there was between each marble because the bread is malleable whereas the marble requires a fixed size.
There's a limit to the pixel density achievable with CCDs. Once the pixelsites get too close together, they interfere with each other electrically and throw off the sensor. CCDs are a nice stopgap measure, but they aren't the bread in the example above.
Having worked for a number of years in the optical astronomy field during the transition from photographic plates to CCD imaging I for one truly appreciate the CCD. No more baking plates in nitrogen and choosing the right emulsion for the wavelength of interest.
Now, the IR sensitivity was a different matter, played hob with the spectrograph we retrofitted with a CCD camera. First order IR overlapping second order blue.....
UNIX: 'cuz you can tattoo it on your knuckles!
Don't you get it....1969. Not yesterday, not the day before....1969. Most of you pups were still your dad's dreams if he was alive then.
I'm surprised it's taken this long to give them a prize.
...every other optical telescope in the world nowadays.
CCDs did more to revolutionize astronomy in the 20th century than the Hubble Space Telescope did. They enabled the HST, but also effectively multiplied the size of all ground-based telescopes by a factor of 10-- although it's not so simple as that, as CCDs provide a host of other advantages really making quantitative imaging possible.
CCDs were huge for astronomy. The "CCD revolution" in the 80's (at least 10 years before most people had really heard of digital cameras) made a big difference.
1969. Back when we were building things. Inventing things. Making things better. We were actually investing in the future then.
Now it would require a "business case" before anyone would be allowed a moment to think about CCD image sensors, much less build them. Some rat fuck middle management asscrack would probably write the group up for "unauthorized use of business resources" and start drawing up requests for department-wide layoffs.
That's of course assuming brilliant people like these men who could "after maybe an hour's work, we went over to the blackboard and we had some sketching there. We went down to our models lab and made one" would get hired in the first place. They'd be declared "overqualified" or lacking "marketable skills" before they were even interviewed.
We were on the doorstep of the solar system almost 40 years ago. Now we're all parked in front of plasma televisions bought on 28% credit watching "reality shows." Talk about toilet-ramming the future. This is what happens when entire generations of education are wasted on purpose. What a fucking waste.
Business isn't willing to pay for products, innovation and careers, so we get brands, mortgage commercials and layoffs.
Unfortunately everyone else that utilized the CCD struck it rich, not Boyle himself. I saw this on Daily Planet yesterday, and how they were sort of joking about it. He didn't get rich because he didn't own the rights to the patent, his company did. That's what happens when you get paid to research / invent.
For he today that sheds his blood with me shall be my brother.
I honestly can't figure out if you're serious or not. Probably doesn't help that you were modded insightful- now you seem to be moderated funny, but I suspect you were not trying to be...
What a bunch of crap. You're buying partially into the romanticization of historical inventors, and ignoring the fact that you only really hear about the people who were NOT shut down, the projects that were not abandoned because of penny pinchers, etc.
Talking about the "good old days" when inventors just picked money from trees, never had to justify research, didn't struggle against powermongering and corporate politics etc...is a bunch of pure, complete, uneducated, knee-jerk bullshit.
Please help metamoderate.
No, they worked for Bell Labs. they are the ones raking in billions on patents. The pleb in the lab never cashes in when part of a big company.
This invention really contributed to keeping the Cold War from heating up - reconnaissance satellites equipped with this technology were very useful to ensuring all sides kept their ends of the bargain during various arms control treaties. Not to mention their usefulness in charting maps and letting us all see from a new perspective.
It's kind of funny when you think about it, but this little invention has broadened our understanding of the entire universe while helping prevent us from blowing each other up down here on earth at the same time. You just can't say that about many things. Great work, gentlemen. Great work.
Surely your professor based his class on the old joke:
A professor stood before his philosophy class and had some items in front of him. When the class began, wordlessly, he picked up a very large and empty mayonnaise jar and proceeded to fill it with golf balls. He then asked the students if the jar was full. They agreed that it was.
So the professor then picked up a box of pebbles and poured them into the jar. He shook the jar lightly. The pebbles rolled into the open areas between the golf balls. He then asked the students again if the jar was full. They agreed it was.
The professor next picked up a box of sand and poured it into the jar. Of course, the sand filled up the remaining space. He asked once more if the jar was full. The students responded with an unanimous 'yes'.
The professor then produced two cans of beer from under the table and poured the entire contents into the jar, effectively filling the space between the sand particles. The students laughed.
Now, said the professor, as the laughter subsided, "I want you to recognize that this jar represents your life. "
"The golf balls are the important things - your family, your children, your health, your friends, your favourite passions - things that if everything else were lost, and only they remained, your life would still be full. The pebbles are the other things that matter like your job, your house, your car. The sand is everything else - the small stuff.
"If you put the sand into the jar first," he continued, "there is no room for the pebbles or the golf balls. The same goes for life. If you spend all your time and energy on the small stuff, you will never have room for the things that are important to you. Pay attention to the things that are critical to your happiness. Play with your children. Take your partner out to dinner. Go out with friends. There will always be time to clean the house and fix the washing. Take care of the golf balls first, the things that really matter. Set your priorities. The rest is just sand."
One of the students raised her hand and inquired what the beer represented.The professor smiled. "I'm glad you asked. It just goes to show you that no matter how full your life may seem, there's always room for a couple of beers."
