The invention discloses an optical-mechanical structure based on a card-type optical system, comprising: a main reflector assembly and a secondary reflector assembly; the primary reflector assembly includes a primary mirror support and a primary reflector; the secondary reflector assembly includes a secondary mirror support, The secondary mirror barrel and secondary reflector; the laser four-quadrant detector is placed between the secondary reflector and the hood, the infrared detector is placed at the rear end of the main reflector, and the center of the main reflector is opened, and an infrared imaging channel is set in the hole. The infrared imaging channel is coaxially arranged at the front end of the infrared detector; the laser is reflected by the main reflector, and then enters the four-quadrant detector after passing through the secondary reflector; after the infrared is reflected by the main reflector and the secondary reflector in turn, it enters the infrared imaging channel to Infrared Detectors. The invention solves the problems of high operation complexity and long assembly period, thereby facilitating the installation and adjustment of the optical-mechanical system, reducing the installation and adjustment cost and the installation and adjustment period.
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...
