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

  • 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.
