This paper attempts to quantify thermal infrared (both longwave and midwave), shortwave infrared, and visible-light sensor performance under different test-chamber fogs. We find that the performance of LWIR imaging is impacted significantly less by light-to-moderate fog than the other two IR sensors and the visible imager. The paper recommends additional fog chamber tests that will be useful for the development of imaging simulation capability that accurately models fog across these wavebands.
