Abstract

A compressive imaging (CI) device for attenuating noise. The CI device may acquire samples during steady state portions of pattern modulation periods, avoiding the disturbing effect of transients that occur at pattern transitions. A CI device may acquire and then average multiple samples per spatial pattern to reduce (deterministic and/or random) zero-mean noise. A CI device may apply a filter to the photodetector signal in the analog domain and/or in the digital domain to attenuate noise components, e.g., noise due to electromagnetic interference.
