基于Zernike多项式的光机耦合数值仿真研究OA

The development of optical systems involves different disciplines such as optics,structure,and thermodynamics,and these disciplines interact with each other.Therefore,this is a multidisciplinary collaborative research and development process.In the initial design stage,it is particularly important to comprehensively consider the coupling relationship among optics,mechanics,and heat.This paper makes a numerical simulation study on the optical-mechanical coupling analysis method in the process of opto-mechanical-thermal integration analysis,focusing on the Zernike polynomial fitting method,and taking the double-lens eyepiece as an example,through the self-developed software Somap,the mirror shape data of the deformed optical system is obtained,and the optical macro file is loaded into the optical design software to analyze the imaging quality of the deformed optical system under external load.The imaging quality decreased significantly.
