Optical Machine Remote Sensing Platform and Its Thermal Field Simulation Analysis

Abstract

Abstract The article introduces a three-axis aerial remote sensing imaging platform that can flexibly and accurately acquire ground target images in the air. Then it analyzes the impact of various complex conditions on the imaging quality, and finds that temperature change is the key factor affecting the imaging quality of the aerial remote sensing platform. The thermal field analysis of the designed optical lens part of the aerial camera was carried out. The thermal field analysis of the lens model in the finite element analysis software was used to extract the displacement vector of each node of the lens under different temperature fields. The mirror data is fitted using the Zernike polynomial program written in the matlab software. And the Zernike polynomial program brings the coefficients of the obtained zernike polynomial into the optical design software zemax for image quality evaluation, and completes the thermal field analysis of the optical system. Do the foundation for further research.
