Incoherent self-interference digital holographic imaging under structured light illumination

An incoherent digital holographic imaging system based on the Michelson interferometer with structured light illumination is proposed, which uses a spatial light modulator (SLM) to realize horizontal and vertical cosine grating illumination patterns to improve the lateral resolution of the imaging system. Using MATLAB software to carry out simulation imaging and numerical reconstruction, the high-resolution reconstructed image under the system is obtained. It theoretically proves that this method can effectively improve the resolution of the incoherent digital holography system. And build the corresponding incoherent light self-interference digital holographic imaging system. By imaging the USAF1951 resolution target, further verified the applicability of the super-resolution imaging method based on structured light illumination experimentally.
