Spectrum Matching and Filtering Technique in Single Channel Dual-spectrum Night Vision System
单通道双谱夜视系统中的光谱匹配及滤光技术

Analyzing spectrum characteristics of night natural radiation,target and background radiation and reflection,linking the spectrum response scope of CCD in low light level night vision system,then the spectrum intersected idea is presented and the project of single channel dual-spectrum night vision system is designed.Explaining the principle of spectrum matching and filtering technique,filtering film is designed and make. Experiment is done to study spectrum-segmentation characteristic of filtering film.The results show that the spectrum-segmentation effect of filtering film which is obtained in single channel dual-spectrum night vision system can improve target distinguish probability.
