Abstract

In the process of airborne camera working in air, the form distortion of optical components caused by ambient temperature will seriously affect its imaging quality. And the technology of thermal-structural-optical integrated analysis is an effective means to evaluate this influence. In this paper, the thermal-structural-optical integrated analysis for the aspheric optical system of an airborne camera is carried out. Firstly, the displacement of each lens rigid body in the thermo-induced optical system and separated it. Then, Zernike polynomial is used as the basis function to fit the form data of each lens under different temperature conditions. Finally, the fitting results are imported into optical software to evaluate the thermal imaging quality of the airborne camera. The results show that both high temperature environment and low temperature environment will affect the modulation transfer function of the camera, and the airborne camera in this paper is more sensitive to high temperature.
