Classification: CPC G  H | IPC G

Claim 5:
6. A system for imaging a target, the system comprising:
an optical modulator configured for applying, at each time of a plurality of times of an exposure window, a respective optical modulation pattern to a received image of the target to output a modulated image;
a camera configured for capturing a single image frame for the exposure window by receiving, at each of time of the plurality of times of the exposure window, the modulated image 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 based on the optical modulation patterns to recover a plurality of recovered image frames each depicting the target at a respective recovered time within the exposure window;
wherein the optical modulator is configured to apply the optical modulation patterns to upshift, in a spatial frequency domain, the received images to different patterned hexagons in the spatial frequency domain.
