摘　　要：光学角偏差和光学畸变是评价深海耐压结构观察窗光学性能的重要参数。现有研究以试验测量为主,而在产品设计阶段并无实物来进行试验研究。本文基于ANSYS有限元模拟的观察窗结构受压变形状态,根据几何光学原理建立光学角偏差和光学畸变计算的理论方法,利用Matlab GUI设计功能建立了交互式光学角偏差计算界面,可便捷地对深海耐压结构观察窗的光学性能进行预测分析。结果显示,观察窗的变形程度对其视野范围、光学角偏差及光畸变均有明显影响。Optical angular deviation and optical distortion are important parameters to evaluate the optical performance of viewport of deep-sea structure.The existing research is mainly focused on experimental measurement,but there is no physical object for experimental research at the design stage.Based on the ANSYS simulation of deformation as well as the theoretical method to calculate optical angular deviation,a GUI interface is designed to calculate the optical angular deviation of viewport,which can be conveniently used in the forecast analysis of viewport window’s optical performance.According to the results,the deformation degree of the viewport window has a significant influence on the field of vision,optical angular deviation and optical distortion.
