right but doesn't this depend on how fast you can send and receive those trillion light pulses? if that can be done in sufficiently short time, the object in motion will have only moved by a small amount, and it will look like it has been elongated in the direction of travel, like a motion blur.
The above is my uninformed and optimistic speculation.
Nope, because a single frame of the video is the result of many trillions of light pulses.
Each time a picture is taken the exposure is so low that the image is incredibly dark. These means they must take lots more and "add them together" to produce a bright image.
If the object is moving it would be impossible since every new image would have the object in a different place, and when you added them together to counteract the fact each image is so under exposed (dark) the object would be blurred.
Right. But the point of high speed photography, like the apple bullet that is disingenuously compared in the video, is that you avoid motion blur. My 200 fps camera can take a trillionth of a second snapshot, with some, um, motion blur
The above is my uninformed and optimistic speculation.
