Abstract: Embodiments of the present disclosure relate to a method for analyzing an imaging quality of an imaging system. The imaging system comprises a spatial light modulator. The spatial light modulator comprises pixel units arranged in an array. The method comprises obtaining a transmittance distribution function of the spatial light modulator based on a structural parameter of the pixel unit, wherein the structural parameter is an aperture ratio. The imaging quality analysis parameter of the imaging system is obtained based on the transmittance distribution function of the spatial light modulator. Then, the imaging quality of the imaging system is analyzed based on the imaging quality analysis parameter.
