Athermalization for Projection Optical System of Long-Wave Infrared Scene Simulator
摘要
Abstract
The infrared scene simulator based on DMD provides the advanced means for the performance testing and evaluation of the infrared system. According to the working principle of DMD, the general scheme of infrared scene simulator is determined, that the illumination system is connected to projection system with the dichroic prism. The aberration properties and optical design and athermal design method of the projection optical system are discussed. A projection optical system is designed, which working waveband is 8~12μm long wave infrared band, F # is 2.8, the field of view is 3°. The projection system was athermalized by optical passive athermal design method at -40-60 ℃. The design result indicates that the optical transfer functions are close to the diffraction limit in the required temperature range, the image quality meet the design requirements, and the system has the characteristics with small loss radiation energy, high resolution and compact structure.关键词
