I saw the first sensors and cameras at EK. I was called in to the Physics Division where the R&D was being done, and I saw all of this. It was amazing. At that time, the camera was a tiny thing, but the supporting electronics occupied a push cart. Fun days. And, this was in the '80s, more than 20 years ago. It was quite secret at that time.
However, the idea was alive, but not brought to fruition. None of these at EK were really carried on, and look what happened!
