I find that solar panels have very fine time resolution as well. When illuminated by the light coming from a CRT monitor and plugged into a 192khz motherboard audio interface, they were able to clearly resolve individual scanlines at 31.5 KHz, each with a sharp illumination peak falling off over microseconds to milliseconds. And IMO plugging a solar panel into an audio jack or cxadc (cheap high-speed 1-channel capture card) is about as realistic as filling a camera sensor frame with a LED's direct light (unsure if indirect reflections are bright enough).

In terms of cameras, I suspect my Pixel 4a's rolling shutter isn't truly continuous, but has blocks of 4 or so "scanlines" (haha) which start and stop recording light simultaneously.
