Performance prediction and computer simulation of staring thermal imaging systems with OTL96

摘要

According to the characteristics of staring thermal imaging systems, a software named OTL96 was completed. The performance curves of the staring thermal imaging systems can be predicted from this software. In OTL96, an improvement method has been developed for calculating the minimum resolvable temperature difference. The critical coefficient is introduced in this method and the prediction result is more consistent with the experiment. OTL96 also has the function of imaging simulation, which can simulate the formation process of the thermal image. This paper illustrates some techniques used in OTL96 and some results will be introduced at the same time.
