Multi-domain foveated compressive sensing system for adaptive imaging

摘要

Described in this disclosure is a space-variant Multi-domain Foveated Compressive Sensing (MFCS) system for adaptive imaging with variable resolution in spatial, polarization, and spectral domains simultaneously and with very low latency between multiple adaptable regions of interest (ROIs) across the field of view (FOV). The MFCS system combines space-variant foveated compressive sensing (FCS) imaging covered by a previous disclosure with a unique dual-path high efficiency optical architecture for parallel multi-domain compressive sensing (CS) processing. A single programmable Digital Micromirror Device (DMD) micro-mirror array is used at the input aperture to adaptively define and vary the resolution of multiple variable-sized ROIs across the FOV, encode the light for CS reconstruction, and adaptively divide the input light among multiple optical paths using complementary measurement codes, which can then be reconstructed as desired.
