Abstract

Different from visible light, infrared optical systems need to consider various effects in order to change the F-number of the system, such as the effect of stray light in the system before and after variable F number, and the effect of cold reflection on the system, which are all effects to be considered. This paper analyzes the technology of infrared variable F number, summarizes the research progress, and the key technology of thermal aperture variable F-number.
