Abstract

In-field stray light caused by surface scattering is a serious problem in many infrared imaging systems. Light that scattered from lenses in infrared imaging system produces a halo of stray light within the field of view and often degrades the performance of an optical system especially irradiated by intensive light such as laser. The experiments are performed by using infrared thermal imaging system, irradiated by CW DF infrared laser. The relationship between the diameter of saturated area on the detector and the incident laser irradiance is obtained, which can be well explained by the point spread function (PSF) of the optics including both diffraction and scattering components.
