2results about How to "The simulation effect is accurate" patented technology

A spatial image simulation method includes the following steps: constructing a DMD-based optical system simulation model; uniformly sampling the angle and intensity of illumination light within the illumination numerical aperture, and selecting a simulation area; for each illumination angle, simulating the complex amplitude distribution of the micromirror in the open state and the complex amplitude distribution of the micromirror in the closed state; obtaining the interference data of the micromirror at the entrance pupil plane for each illumination angle; obtaining the spatial frequency spectrum at the exit pupil plane for each illumination angle; simulating the corresponding light intensity distribution based on the complex amplitude distribution for each illumination angle, and superimposing the light intensities corresponding to all illumination samples to obtain the final light spot result. Based on the actual working scenario of the DMD, and considering that the tilt angle of the DMD micromirrors has a significant impact on its diffraction, the introduction of various tilt-induced phase differences and tilt factors results in more accurate simulation effects.
