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).
