The invention discloses an asymmetric reflection optical system based on a micro nano optical surface. The system comprises a projector array, a spherical reflector A, a spherical reflector B, a micronano optical surface combined device, a target space motion simulator and a tested optical detector; the spherical reflector A and the spherical reflector B are arranged in a back-to-back way; and the micro nano optical surface combined device is arranged in a common focal plane of the spherical reflector A and the spherical reflector B. The asymmetric reflection optical system gives full play toperformance advantages of the micro nano optical surface and is no longer limited by the transmitting waveband, the system can be arranged more flexibly, requirements for optical radiation scene simulation in a complex background can be met, and directed combination of the pupil can be realized. The spherical reflector system arranged in a concentric way is used, aberration can be eliminated in the whole wide work spectrum range, and the system resolution is improved.
Description
technical field [0001] The invention relates to the technical field of optical systems. More specifically, it relates to an asymmetric reflective optical system based on micro-nano optical surfaces. Background technique [0002] With the popularization of a new generation of optical imaging detection devices, multi-object / broadband complex targets and background environments have put forward more urgent requirements for a multi-beam compound hardware-in-the-loop simulation system with corresponding simulation capabilities. The complex optical radiation scene in this kind of optical object hardware-in-the-loop simulation system has different spectral characteristics, and must reach the entrance pupil of the optical detection device under test at the same time to realize the performance assessment of the new generation of optical imaging detection system, so it is impossible to use a single projection To realize the instrument, the optical multi-aperture composite method of c...
