Infrared visual emulation system and radiation field joint adjusting and control method thereof

Abstract

The invention discloses an infrared visual emulation system and a radiation field joint adjusting and control method thereof, and the joint adjusting and control problem of an infrared digital scene and an infrared target simulatorissolved. According to the infrared visual emulation system, DMD control in the emulation system is synchronized with a drive circuit control imaging device and image frame between infrared digital scene units. Image radiant brightness of the infrared digital scene units and the blackbody light source temperature are adjusted to obtain joint adjusting and control ofthe emulation system. According to the radiation field joint adjusting and control method, on the basis of the emulation system, the radiant brightness of the infrared digital scene units and the blackbody light source temperature of the DMD infrared target simulator, and the spatial light modulator transmittance relationship are established item by item, an exit pupil radiant illuminance transfermode of the target simulator is established, the quantization range of the image radiant brightness and the range of the blackbody light source temperature are determined, a radiation regulation model of a whole link path of the system is established, a blackbody radiant brightness and temperature comparison table is manufactured and found out, regulation model parameters are determined, and radiation field joint adjusting and control is obtained. The infrared visual emulation system is used for infrared scene image emulation.
