The invention discloses an optical-mechanical structure based on a card type optical system. The optical-mechanical structure comprises a primary reflector assembly and a secondary reflector assembly,the primary reflector assembly comprises a primary reflector support and a primary reflector. The secondary reflector assembly comprises a secondary mirror bracket, a secondary mirror barrel and a secondary reflector; a laser four-quadrant detector is arranged between the secondary reflector and a hood, an infrared detector is arranged at the rear end of the primary reflector, a hole is formed inthe center of the primary reflector, and an infrared imaging channel is arranged in the hole and coaxially arranged at the front end of the infrared detector; the laser is reflected by the primary reflector, penetrates through the secondary reflector and then enters the four-quadrant detector; and the infrared rays are reflected by the primary reflector and the secondary reflector in sequence andthen enter the infrared imaging channel to the infrared detector. According to the invention, the problems of high operation complexity and long assembly period are solved, so that the optical-mechanical system is convenient to install and adjust, the installation and adjustment cost is reduced, and the installation and adjustment period is shortened.
Description
technical field [0001] The invention belongs to the technical field of optical-mechanical assembly and adjustment, and relates to an optical-mechanical assembly and adjustment method based on a card-type optical system. Background technique [0002] The dual-band Cassegrain optical design is the key technology of the seeker system, which is related to the complexity, processing difficulty and final performance of the optical-mechanical system, while the optical-mechanical structure design and assembly technology are the key to achieving optical performance. Technology, its rationality determines the ultimate performance and cost of the system. Among them, the reflective cassette system has the characteristics of large aperture, long focal length, and multi-band. It includes two reflectors, the primary mirror is a concave aspheric mirror, the secondary mirror is a convex aspheric mirror, and the center of the primary mirror has a hole. The post-installation quality of the pr...
