基于CODE V和LightTools的成像系统初级鬼像分析

Primary ghost image analysis of imaging system based on CODE V and LightTools

  • 摘要: 对鬼像的基本概念和形成原因进行了介绍与分析,提出了利用光学设计软件CODE V定性分析与光机适配性软件LightTools定量分析相结合的鬼像仿真分析方法。使用lightTools软件仿真与系统探测器归一化真实响应照度值相比较找出鬼像路径,给出改进措施。对验证实验中给定的电视成像光学镜头的鬼像路径进行计算和仿真,计算结果表明,镜头轴上鬼像路径的归一化响应照度为3.5×10-5,小于探测器的归一化响应范围9.85×10-5~1,探测器无响应,即不产生鬼像,证明该仿真分析方法正确可行。

     

    Abstract: Basic concept and cause of ghost image are introduced and analyzed. Ghost image simulation method is put forward, which is based on qualitative analysis of optical design software CODE V and light machine fitting software LightTools quantitative analysis. Comparing lightTools software simulation results with normalized true response illumination value of system detector, ghost path is found and improvement measures are given. Ghost path of TV imaging optical lens given in verification experiment is calculated and simulated. Results show that normalized response illumination of ghost path on lens axis is 3.5×10-5, which is less than 9.85×10-5 ~ 1 of the detector and detector does not respond and produce ghosts. Simulation analysis method is proved to be correct and feasible.
