Abstract

The current semi-physical simulation testing of optoelectronic products requires the simulator to meet the requirements of full band, high accuracy and portability.In response to this demand,a full-band target simulator that can be used on a five-axis turntable was designed.The collimating optical system of the target simulator adopted off-axis reflective structure design, and the radiation simulation source adopted infrared and visible light composite radiation sources; the infrared radiation source and the visible light radiation source adopted the coaxial mode, the structure was compact, and the temperature control accuracy can reach 0.1°C.In order to ensure the imaging quality of optical products, this paper designed the target simulator with exit pupil diameter Φ200mm, exit pupil distance 700mm, parallel difference 8.5", transmittance 0.8@632.8nm. Targeted on different test requirements,designed a variety of shapes such as point hole, four bar, cross and multi-target.Aiming at the problem that the optical axis of the infrared and visible light sensors of the tested photoelectric product is not at the center of rotation of the five-axis turntable, physical translation is used to achieve the connection between the target simulator and the pupil of the sensor optical system of the tested photoelectric product.The target simulator was put into use as soon as the design was completed. After using a variety of optoelectronic products, the feedback was good and met the design requirements.
