摘要
对轴向温度梯度、径向温度梯度对大口径光学窗口面型的影响加以介绍，并运用ansys软件分析大口径光学窗口在两边存在温度差、压力差下的形变.用Zernike系数将ansys软件分析结果与Zemax软件连接，在Zemax软件中仿真光学窗口在15～27°温度范围内6种工况下的形变对平行光管像质的影响.
Abstract
The influence of axis and radial temperature gradients on the deformation of optic window with large aperture is discussed. The optic window deformation with temperature and pressure differences on the both sides is analyzed by ansys program. Zernike polynomial, as an interface tool, connects the ansys program simulated results with the optic design program. In zemax program, the influence of optic window deformations at 12～27℃ on the optic system image quality are analyzed.
