The Fastest Camera in the USA

My guess is that it uses an electronic shutter since a mechanical shutter is unrealistic. The sensor is always on, but the image is sampled 2 million times a second.

oh,

not only 2 milion f/s, this speed has been completed 60's last centure.

some of them use koer box as shutter.

"The fastest speed camera finished in USA, 2billion frames in one second!So wonderful, how do they do it? Can anyone tell me more detail about it?"

Did you mean?

A Billion Pixels Per Second

Four trillion bits per second is the fastest, devide four trillion by bits in picture?

Those types of fast camera are sometime called streak camera, and can store image at rapid speed in ps time as the information from image is steed and stored at different placed on the fast phosphor. Image readout is often slow. It is like capturing the fast information in a digital storage oscilloscope and viewing it slowly. Several GHz signal can be viewed using this technology.

I have worked on parallel direct frame imaging technology for 100 million frame per second using fiber optic pixels and now this technology can easily reach 1-10 billion frames per second rate. Not that such camera are of any great use for public, but these are only tools for something otherwise happening in such a short time and is impossible to look at. It is all now possible as long as there is enough money for developing such a system. These are no-longer called impossible technologies and not even special one. They are just technologies and on demand for money.

I can easily make such ultrafast imaging system. Keep looking at magazine from Lauren www.photonicsspectra.com and you will find many others who may come up with us system sooner or later.

Do you have any links to the original story? I thought we were doing well when we made a camera running at 500 million fps last year but it looks like we will have to try harder.

That is not bad at all at 500 MFPS. Unless you have need for supper speed in some experiment, you need not go very high speed. Find a buyer and I can make one fatser than that. I find no taker for such technology in India.

I found the original story about the university of Wisconsin & I don't feel so bad now as it sounds like they are referring to a streak camera as Shyam suggested. We already make femtosecond streak cameras, our 500m fps camera was an intensified CCD camera.

There are many ways to make those fast image storage devices. Often you end up handling single or few photons per pixel image, so you do insert some fasts light to electron converter and electron multiplier in between. Fastest electron multiplier is 100ps to get you 10^7 electrons per electron. You can also use photon multiplier like laser amplifiers. Using electron multiplier is cheaper and is very effective. You can also steer the electron beam very fast and hence you can record the information of the image wherever you like.

With emerging technology of quantum dots, switched quantum states and nano materials helping the design of the matrix, we should be able to have new technology for imaging and they will be very effective and damn cheap. How soon all that will come up is not very important but I can see all that waiting to happen.

I think the human brain stores the signature in similar manner but only difference is that we store raw information in a camera and brain stores quantized filtered information. Regeneration of information in the brain is like a wave function spread over brain space of neurons. We are yet to get an intelligent imaging system of that kind but is not impossible to build all that in semiconductor.

There is lot to imagine and most of my work has been from imagination to reality. It is all right to use developed known technology as most of you are engineers. I prefer to dream the new world and I work on all those ideas from dreams. It is much easier to me to work in that way. I do not have to read others books. All I have to do is to eat well and go to sleep and next day I have a new idea to work on. There must be many people like me.
