Abstract

Based on compressed sensing, snapshot compressive imaging aims to optically compress high resolution images using low resolution detectors. The challenge is the generation of the simultaneous optical projections that can fulfill compressed sensing reconstruction requirements. We propose the use of aberrations to produce point spread functions that can simultaneously code and multiplex partial parts the scene. We explore di erent Zernike modes and analyze the corresponding coherence parameter. Simulation and experimental reconstruction results from 16X compressed measurements of natively sparse and natural scenes demonstrate the feasibility of using aberrations, in particular primary and secondary astigmatism, for simple, e ective single-shot compressive imaging.
