Question

How do ultra high speed cameras (such as the Phantom cameras) work?

In: Technology

Answer 1

There are some types of memory which can be filled up very fast, but like RAM in a PC, they are only temporary. So a high speed camera records a huge number of frames per second for a very short burst, then you need to transfer that data off the camera memory before recording the next high speed burst.

You can easily need to be storing gigabytes of data per second, so with high end cameras most of the expense is getting the memory and memory controllers right.
