Trillion-frame-per-second video - Klaus - 12-13-2011
Quite cute albeit a little expensive to setup maybe ....

Well, even a Sigma can catch some sort of light, doesn't it ? ;-)

Proably be going for $30 or so at the 2035 MIT flea market

Few weeks ago DPR had video recording posted of the lecture of CMOS inventor. He was explaining that the future of the noiseless cameras will be some method of photon counting at each photo site. The way he said it soundeed like scifi, now there is prototype that can do it.

Will it be like measuring only the light that hits it, not "gathering" it like now?
Compare the sensors now to a bucket that catches the water and can only catch so much before it's full, the bigger the bucket, the more it catches (the bigger dynamic range). And this new thing just is a mechanism that just measures the amount of weather passing through, so it can "catch" any amount, meaning any amount of dynamic range, more dynamic range the longer you expose.
If so, I've been wondering why sensors don't work like that <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='
' /> but I know nothing about electronics though, so even if it's a no-brainer for someone working with sensor technology why they're not working like that, i wouldn't know.

It sounds like it. If you find the time go ahead and watch his presentationit was quite interesting.

So basically it can't do many frames per second at all. They just follow different sequential pulses of light and then put them all together as if it is one event. Hmm.. pretty lame, then.

They still need to be able to precisely time their shots to create such a video.
