Compressed sensing hyperspectral coding structured light imaging system and method

The invention belongs to the technical field of spectral light field imaging, and particularly relates to a compressed sensing hyperspectral coding structured light imaging system and method, and the system mainly comprises an illumination light generation module, a spectrum modulation module, a space coding module and an image collection and reconstruction module. Wherein the illumination light generation module is used for generating parallel broadband light beams after collimation and band-pass filtering; the spectrum modulation module uses a spatial light modulator A (which can be a digital micromirror device, a liquid crystal spatial light modulator and the like) to modulate the spectrum of an illumination light beam, realizes beam splitting and beam combination through two same dispersion elements (which can be dispersion elements such as a prism, a grating and the like), and outputs parallel illumination light beams of spectrum coding; the spatial coding module generates stripe-structured light to illu
