Super-large visual field multi-target scenery simulation system

Abstract

The invention provides a super-large visual field multi-target scenery simulation system. The super-large visual field multi-target scenery simulation system comprises a light source system, a target system, a collimating system, a rotary spectroscopy system and a control system, wherein the light source system is used for providing a uniform surface light source which can generate target light beams through the target system, the target light beams pass through the collimating system and then are divided into more than two paths of parallel light beams through the rotary spectroscopy system, and the parallel light beams are incident into an imaging system to be tested. The super-large visual field multi-target scenery simulation system can be used for solving the problems that the production cost is high caused by a plurality of collimators, a visual field for scenery simulation is too small caused by a movement mechanism on a focal plane, and the like. The system is concise in structure, and can be used for realizing the simulation of a multi-target large visual field scenery, so that the acquisition cost of testing equipment is greatly saved. Under the condition of not adding the collimating system, the simulation of a double-target scenery is skillfully obtained. By expanding a beam splitter prism, the simulation of more targets also can be realized, so that the super-large visual field multi-target scenery simulation system is truly initiative in China.

Description

technical field [0001] The invention belongs to the field of optics, and relates to a multi-target scene simulation system with a super large field of view, which is specifically used for scene simulation of a large field of view optical system in a laboratory. Background technique [0002] As an important part of space imaging equipment, ship optical system, shooting range photoelectric measurement equipment, weapon control system and laser communication system, the ultra-wide field of view optical system plays an extremely important role. When testing the imaging quality, tracking performance, and magnitude detection capabilities of the ultra-wide field of view optical system, special testing equipment is required. On the one hand, this device needs to meet the requirements of a large field of view, and on the other hand, it needs to simulate moving targets, both of which are indispensable. [0003] For example, when performing multi-field magnitude simulation on a star s...
