摘要
对于远距离、大视场、多个运动目标的光电跟踪,现有光学系统形式难以同时兼顾大口径、大视场与高角分辨率的要求。通过模仿人眼小凹转动视觉生理机制,设计了一种轻型物方扫描校正镜组,具有中红外成像与激光测距的共口径同轴五反式新型光学系统。该光学系统主镜口径为1000 mm,瞬时扫描有效口径为600 mm,最大视场角达到20.7°,中波红外成像传感器像元角分辨率优于13 mrad,激光测距单元作用距离达到20 km。该新型光学系统具有大视场范围,可同时对6个以上远距离高速运动目标进行跟踪。
Abstract
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.
