Is this like that one that was able to film photons in slow by just filming a very short laser pulse at a slightly different time each frame? That was a cool concept, I’ll have to look more at this one
After skimming through the article and at the abstract and introduction of the article in Nature, it seems that unlike those technique you mentioned, this is really a single-shot real time imaging.
I’m not sure what you’re describing…. Is that like stop motion animation, but instead of moving the subject between captures, you just change the delay between firing the laser pulse and the shutter?
Yeah basically. It doesn’t try to record a single laser pulse interacting with the scene in one shot, but rather slightly adjusts its shutter offset to record another identical pulse in a slightly later position. Since the pulses are basically the same each time, the light will interact the same way with the stationary scene and you can reconstruct the movie from there. You can watch videos by searching 1 trillion FPS camera since that was how it was labeled by pop-science at the time.
