建立了一套基于刀口灰度图红外探测的实验装置,对红外场景生成器的空间分辨率进行了测试。首先通过被测红外场景生成器产生带有刀口标志的红外图像,然后利用红外热像仪采集红外场景生成器所成的红外图像,通过对采集到的红外热图的数据处理,实现了对红外场景生成器空间分辨率的测量。测得的红外场景生成器的空间分辨率为5lp/mm,标准误差为0.04。 A set of experimental device based on the edge grayscale infrared detection was set up to test the spatial resolution of infrared scene generator. Firstly, the infrared image with the knife-edge mark is generated by the measured infrared scene generator, and then the infrared image generated by the infrared scene generator is acquired by the infrared camera. By processing the collected infrared heat map data, Scene generator spatial resolution measurement. The measured infrared scene generator has a spatial resolution of 5 lp / mm and a standard error of 0.04.
