Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a single-pixel microscopic imaging method and system based on Koehler illumination. Background technique [0002] Single-pixel imaging technology is a new computational imaging method developed in recent years, which mainly relies on the intensity fluctuation correlation of two or more light fields to obtain image information of target objects. Due to the advantages of strong anti-interference, high detection sensitivity, super-diffraction resolution limit, and simple optical path structure, single-pixel imaging technology is favored in the application fields of optical imaging, quantum imaging, and information science. In the single-pixel imaging process, the light source modulated by the spatial light modulator is used to directly illuminate the target object to be measured, and then a photodetector without spatial resolution is used to receive the total light intensity...
