Abstract

The present invention proposes a dual-field transmissive multi-sensor single-aperture optical system, which includes a wide-spectrum common transmissive telescopic component 1, an FSM component 2, a spectral splitting component 3, a laser component 4, a TV relay component 5, a CCD component 6, Thermal image relay assembly 7, infrared detector assembly 8; the incident light reaches the spectral beam splitting assembly 3 through the flat reflector 2-1 of the wide-spectrum common transmission telescopic assembly 1 and the FSM assembly 2, and is transmitted through the first beam splitter 3-1 Enter the thermal image relay component 7 of the small field of view, and finally reach the infrared detector component 8; reflect and enter the second beam splitter 3‑2; the reflected light is reflected by the second beam splitter 3‑2 to the laser reflector 4‑1, and finally reaches the laser Component 4; transmission enters the TV relay component 5, and finally reaches the CCD component 6. The system has a high degree of integration, a dual-field of view coaxial fusion design for search and tracking, and can realize the stabilization of the line of sight of each sensor. aberration problem.

Description

technical field [0001] The invention belongs to the field of optical technology, and relates to a multi-spectral multi-sensor common-aperture optical system, in particular to a dual-view field transmissive multi-sensor single-aperture optical system with two large and small fields of view. Background technique [0002] With the development of informatization, networking, and coordination of optoelectronic equipment requirements, the optoelectronic system will develop in the direction of multi-function, high performance, long-range vision, and information fusion, and the optoelectronic load must be lightweight and miniaturized to improve the optoelectronic system. Integration. [0003] The common photoelectric sensors equipped with domestic photoelectric systems include televisions, infrared thermal images and lasers. The layout of each sensor adopts an independent modular separation method, each with its own optical system and window, resulting in a relatively large volume a...
