NON-RAYLEIGH SPECKLE FIELD-BASED CORRELATED IMAGING SPECTRAL CAMERA AND IMAGING METHOD THEREFOR

摘要

A non-Rayleigh speckle field-based correlated imaging spectral camera and an imaging method therefor. A device comprises a front imaging camera (1), a beam splitter (2), a bandpass filter (3), a monitoring detector (4), a polarizer (5), a beam splitter (6), a spatial light modulator (7), a surface array detector (8), and a computer (9). By utilizing the reversible feature of a light path, a non-Rayleigh speckle field can be generated in a lens-less condition and be applied in a compression sensing-based correlated imaging spectral camera, where the utilization of a super-Rayleigh speckle field for imaging increases the quality and resolution of a reconstructed image in a low signal-to-noise condition.
