Design of a dynamic target simulator optical system with a large FOV and long exit pupil distance
According to new generation missile test and detection requirements, it is necessary to introduce hardware-in-the-loop (HIL) simulation technology to realize the performance test of the seeker. This paper introduces the concept of secondary imaging and uses the method of focal distance allocation so that the optical system field of view (FOV) can still be greater than 6°, under the condition that the exit pupil distance is larger than 800 mm and a high-quality lighting system is designed. The design results show that when the exit pupil distance of the system is 1000 mm and the FOV is 6.4°, the modulation transfer function (MTF) of the system is 60l p/m m>0.4, and the distortion is less than 0.1%. The uniformity of the illumination system is greater than 90%, meeting the requirements of the design index.
