ABSTRACT

According to the working requirements of the dynamic star simulator, the optical passive thermalization elimination method is used to achieve the purpose of athermalization. Using CODE V optical software designed a set of refraction primary imaging optical system composed of different thermal characteristics materials and corrected axial aberration and other aberrations. The software used to analyze the imaging quality of the optical system at -40°C ~ 60°C, the results show that the optical system in the full temperature range of the diffuse diameter of 20.5μm, better than the Airy disk diameter and pixel size ; The full field modulation transfer function is higher than the diffraction limit at a spatial frequency of 20lp/mm, and the imaging quality is excellent; the energy distribution is over 65%; The defocusing amount at each temperature is all less than the depth of focus, which satisfies the requirements of the star simulator.
