World's Fastest Camera Captures 4.4 Trillion Frames Per Second
Diggester writes Japanese researchers have recently designed a motion picture camera which is capable of capturing 4.4 trillion frames per second, making it the fastest camera in the world. The technique that allows for such speed is called STAMP (sequentially timed all-optical mapping photography). The research paper, published in the journal Nature Photonics has the full details.
This technology sounds totally cool. I'd like to see them use it to take pictures of somebody viewing the shitty Slashdot Beta site. They could capture the user's extreme boredom as this user waits for the shitty Beta site's page and all its shitty JavaScript and CSS crap to initially load. Then they could capture the trillionth of a second when the person notices that it's the shitty Beta site rather than the Classic site, and the person's anger starts to grow. The photos would progressively show the anger turning into madness, and then finally utter and complete disappointment and despair once the shitty Beta site has finally loaded. The photos could also capture the formation and flow of the very first of many teardrops to cascade down this poor victim's cheeks as the user struggles in vain to read the stories' small text with poor contrast. These trillions upon trillions of frames of total anguish could be examined in excruciating detail, so the awful nature of the Slashdot Beta site could be truly comprehended.
First FTA: There's a mention of a previous camera...
"Back in 2011, researchers from MIT created a high-speed camera that captured light passing through an empty bottle in slow motion by acquiring visual data at one trillion frames a second – to the STAMP cam, more than four times faster than this, even the speed of light could be as stimulating as watching paint dry."
That's misleading. The camera in 2011 didn't do amazingly high FPS capture. What it did have was very short capture with precise timing. That video of a laser moving through a bottle was actually thousands of successive laser shots. More like stop-motion than video.
Now this camera I see fewer details on. I do see that one thing it seems to do is to divide a laser with a prism and use the separation to make virtual frames by using different receptors.
Let me make an analogy. If you took a normal RGB color sensor from a camera, and exposed it, and during that exposure you fired a red flash, then a green flash than a blue flash one after the other. Take your resulting picture and break it into three by color and you have 3 "frames". They appear to be doing this with a large number of wavelengths.
