Abstract
A reasonable optical system for Micro-electro-mechanical System (MEMS) based on digital sun sensor was designed. Based on scalar diffraction theory, the imaging model of the optical system for the sun sensor with a structure of circular aperture was developed. A computer simulation was carried out to obtain the parameters of optical system in the distance of 4 mm, aperture of 50 μm and the space between holes of 700 μm. The ground experiment was carried out for this optical system with a sun simulator, and the results show that the optical system is designed well and can meet the requirements of miniaturization and high accuracy of a sun sensor.
