Application of optical system simulation software Seelight in adaptive optics

光学系统仿真软件Seelight是一款可以模拟光束产生、大气传输与自适应光束控制等光学系统的具有自主知识产权的系统仿真软件,为光学系统应用研究提供了有效的仿真工具。本文首先介绍了Seelight软件的基本构架、运行界面和主要模型库包含的模块,并利用自适应光学相关的基本模型搭建了自适应光学仿真系统,模拟了PZT变形镜模块和哈特曼波前波传感器模块构成自适应光学仿真系统通过校正光束大气传输的波前畸变来提高远场光斑的光束质量的过程。验证了在不同的湍流强度下,自适应光学仿真系统的校正效果随着湍流强度的增加,校正残差大幅增加。利用Seelight软件可以对包含自适应光学系统的各种光学系统进行仿真建模,并可以对系统进行有效的验证分析和优化设计。

The optical system simulation software Seelight is a system simulation software with independent intellectual property rights which can simulate beam generation, atmospheric transmission and adaptive beam control. The software provides an effective simulation tool for the application fields of optical system. In this article, we introduce the basic structure of Seelight software, the running interface, and the main modules of model libraries. Using the basic models of adaptive optics to build adaptive optics simulation systems, including the PZT deformable mirror module and the Hartmann wavefront sensor module, which improves the beam quality of the far field by correcting the wavefront aberration due to beam propagation through atmosphere. The correction effect of adaptive optics simulation system is verified under the different turbulence intensity, it is clear that correction residual greatly increased with the increasing of turbulence intensity. The Seelight software can be used to simulate various optical systems including adaptive optics system, and the system can be validated and optimized.
