摘要
在对微光装备分辨力测试和红外装备MRTD测试系统进行分析的基础上, 提出了微光和红外融合装备的分辨力测试方案, 利用现有的红外MRTD测试系统, 通过改造光源、光源的入射光路和靶板, 建立了微光与红外融合图像的图像分辨力测试系统, 并对该方案进行了分析。分析结果表明, 改造后的测试系统同时实现对红外的反射和对微光的透射, 对红外温差的测量精度接近0.01 K, 对微光照度的测试精度可以达到1 lx, 对融合图像分辨力的测试满足1/62≈0.891的倍数递减要求。
Abstract
Based on the analysis of the resolution test system for low-light level(LLL) vision equipment and the multi-resolution time domain (MRTD) test system for infrared equipment, the conception of resolution test scheme for LLL and infrared image fusion equipment was proposed . The exiting equipment of infrared MRTD test system was utilized, the resolution test system of the LLL and infrared fusion image was established by modifying light source, incident light path and target plate , and the analysis on the scheme was conducted.Results indicate that the modified test system can both realize infrared reflection and low-light projection. The measurement accuracy of infrared temperature difference is close to 0.01 K, and the measurement accuracy of low-light illumination can reach 1 lx. The test of fusion image resolution meets the requirement of multiple decrement(1/62≈0.891).
