Design of Wide Field-of-View and Multi-Targets 3D Imaging Optical System with Coaxial Five Mirrors
Concerning to long-range, wide-field and multi-targets electro-optical tracking system, it is difficult to take account of the requirements of large-aperture, wide field-of-view and high angular resolution at the same time in the form of existing optical systems. By mimicking the visual physiological mechanism of the roving fovea of human eye, a new common aperture coaxial five mirrors medium wave infrared (MWIR) imaging and laser radar optical system with light-weighted object orientation scanning corrector optics is designed. The primary mirror aperture of this optical system is 1000 mm, the instantaneous scanning effective aperture is 600 mm, the maximum field-of-view angle is 20.7°, the angular resolution of the MWIR imaging sensor is higher than 13 mrad, and the operating distance of the laser radar reaches 20 km. The new optical system has wide field-of-view, which can track more than six long-range fast-moving targets at the same time.
