Classification: CPC G  H | IPC G

Claim 12:
13. A system for imaging a target, the system comprising:
one or more beam splitters configured for separating a received image of the target into a plurality of optical paths each having a different optical length, each path including a respective optical modulator configured to output a respective modulated image of the target;
one or more beam combiners configured for combining the modulated images;
a camera configured for capturing a single image frame for an exposure window by receiving, at each of time of the plurality of times of the exposure window, an output from the one or more beam combiners of an optical combination of the modulated images of the target; and
a demodulator implemented on a computer system comprising at least one processor, wherein the demodulator is configured for demodulating the single image frame to recover a plurality of recovered image frames each depicting the target at a respective recovered time within the exposure window;
wherein demodulating the single image frame comprises performing selective filtering in the frequency domain to isolate the recovered images using data specifying modulation patterns of the optical modulators.
