# What are the difficulties of constructing a camera with $3.10^{8}$FPS? [closed]

what are the difficulties of constructing a camera with $3.10^{8}$ frames per second (FPS)? In order to study the nature and speed of light, can we construct a camera with $3.10^{8}$ FPS?

• There are already very high-speed mechanical and, more recently, electronic framing cameras that can operate in that range. I seem to recall that the mechanical high-speed framing camera that I once used in experiments was capable of recording images at speeds up to at least 80 nsec per frame, and that was many years ago. – Samuel Weir Sep 24 '17 at 16:28

No difficulty. There is already camera that can captures more than $10^{15}$ FPS (i.e. $<1fs$). The real difficulty is to store lots of frames because of the memory limitation, which means the time duration is very short.
