Abstract

Digital holographic microscopy (DHM) is an efficient optical measurement and imaging technology with the advantages of non- invasion, non-damage, high sensitivity and high resolution. However, its resolution is still limited by the diffraction limit of the system. The structured light illumination microscopy (SIM) is a good super resolution imaging technology, which obtains high frequency information of objects by changing the lighting mode to achieve improved imaging resolution. In order to discuss the factors that affect structured light phase imaging, we first simulated the entire imaging process of a structured light digital holography system using Matlab software, and then systematically analyzed the effects of four factors, structured light spatial frequency, loading direction, modulation level, and noise level, on the imaging situation, and reached corresponding conclusions. The above research results can provide a reference for the study of structured light phase imaging methods.
