红外扫描成像系统中冷像的分析和控制
Analysis and Control of Narcissus Effect in Scanning Infrared Systems
摘要
提出了一种基于准近轴光线追迹的冷像噪声的快速分析方法，给出厂适用于这类非对称光学系统的准近轴光线追迹公式，介绍厂在光学系统自动设计阶段控制或消除冷像噪声影响的方法.这些分析和控制已全部在北京理工大学研制的GOSA软件中实现.
Abstract
A fast analysis method for the Narcissus effect based on pseudo-paraxial raytracing is proposed. The definitions and tracing formulae for the pseudo-paraxial rays are given. The Narcissus induced temperature reduction for the axial point and the Narcissus induced temperature variation over the field can then be calculated. Different methods of reducing the Narcissus effect during automatic design of the optical system are discussed. All the analyses and controls are implemented in the GOSA (General Optical System Analysis and optimization) program developed at Beijing Institute of Technology.
