Aiming at the current testing requirements of optoelectronic products, a portable target simulation system with adjustable radiation band was designed.The optical design of the system adopted a total reflection structure, and the radiation source adopted a combination of black body and visible light, covering the wavelength band of 0.4 μm to 12 μm.In order to facilitate the use of the product, an electronic shutter was installed to realize the disappearance and appearance of the target. By switching different wavelength filters, the switching and combination of medium wave, long wave, visible light and other radiation bands could be realized. The final design achieved an effective aperture of Φ200mm, a field of view of 2°, a parallel difference of 9", and a focal length of 1500mm.The target simulator works well after delivery
