Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optimization method, system and storage medium of a projection system. Background technique [0002] In the design of digital light processing (Digital Light Processing, DLP) projection optical lighting system, it generally includes four parts: collimation system, light combining system, uniform light system and relay system. The collimation system will collect the light from the light source and The collimated light is parallel light, and the light combination system will collimate the light at each wavelength to synthesize a beam of light. The uniform light system generally uses a compound eye element, and the combined light passes through each small lens unit of the compound eye system to split and homogenize the light, and finally passes through the center Following the shaping of the system, the light beam is uniformly irradiated on an illuminated surface of a cer...
