Abstract

The design of the dual-channel projection collimator for the dynamic infrared scene projector is introduced in this paper. The optical system is the combination of a telescope system and two imaging systems of the target channel and the inference channel. The scenes from two optical channels are combined into one scene by the beam combiner. The optical system consists of twelve elements and aspheric surfaces are used in the imaging system to increase the image quality and simplify the configuration of the optical system. The optical system is capable of operation over the 8~12μm wavelength range and testing an infrared seeker over 12°field of view (FOV). The effective focal length of the optical system is 228.3mm and the exit pupil distance is 800mm.The image quality and the formats of the system meet the requirements of the projector.
