We had rooms full of image processing equipment at the Digital Signal Processing lab at MIT. Prof. Troxel was a cool guy and loved gadgets. We frequently build large custom boards to do simple stuff like the equivalent of the levels feature in photoshop. One of the guys there got his PHD in EE, his specialty was Charge Coupled Devices (CCD's as we now know them), a relative novelty at the time. He and I started a consulting company to solve problems with CCD subsystems.
My first digital image was an IR image from a top secret (at the time) camera. Its IR was quite sensitive but they were having problems with distortions from the mirror assembly which they wanted us to solve. They paid us alot of money to solve the problem in two weeks, I guess they were under a huge time pressure to get this to their customer, which we guessed was the DOD due to the high clearance we had to get. When we solved the problem, I took a picture of myself to test the sensitivity of the camera. I was told that it would detect the residual heat from my hand after I had placed and removed it from my chest. Well, I did that and was amazed. Not only could I see a ghostly image of my hand, but I could see through my shirt and many of my larger arteries/veins were visible. My face looked like the face of an alien with my veins, bone structure and what looked like fatty deposits or something visible. I am going to try to dig that pic up and post it here. rg [EMAIL PROTECTED] wrote: > The first digital imaging I did was with a Computer Eyes card in an > Apple IIGS with 256K RAM and 1 megahertz clock speed.
