Description

technical field [0001] The invention relates to an optical athermalization design effect detection system, in particular to an image processing-based optical athermalization design effect detection system. Background technique [0002] In recent years, infrared imaging systems have been widely used in both military and civilian fields. The development of technology has higher and higher requirements for infrared imaging systems, usually requiring the system to work in a wider temperature range. Due to the large temperature coefficient of refractive index dn / dT of infrared optical materials, the imaging quality of infrared optical systems is easily affected by the temperature of the working environment, and the athermal design has attracted more and more attention from scientific and technological personnel. At present, there are few domestic studies on the detection of athermal design effects, most of which are theoretical studies and aberration analysis using optical desig...
