Abstract

The invention discloses an automatic flexible assembling and calibration platform and method for a meter-scale reflector. The automatic flexible assembling and calibration platform for the meter-scalereflector comprises a base and a rotary table rotatably mounted on the upper portion of the base; the rotary table comprises an assembling panel and a jacking plate; a positioning pin which can be close to or far away from the jacking plate is arranged on the assembling panel in the circumferential direction of the jacking plate; a flexible cleaning pad is arranged on the upper surface of the jacking plate; and lock screw assemblies are arranged on the two sides of the assembling panel. By adopting the automatic flexible assembling and calibration platform and method for the meter-scale reflector, the problem in automatic flexible batch assembling and calibration of the meter-scale reflector is solved, the cleaning problem caused by manual intervention is avoided, the assembling and calibration efficiency is greatly improved, the pre-tightening forces in all positions of the reflector are uniform, the front-wave error caused by reflection is reduced, and the assembling and calibrationquality and stability of the reflector can be improved; and meanwhile, the assembling and calibration platform and method can be popularized and applied to the assembling and calibration process of other precise optical elements.

Description

technical field [0001] The invention belongs to the technical field of precision assembly and calibration of meter-scale optical elements, and in particular relates to an automatic flexible assembly and calibration platform and an assembly method for meter-scale mirrors. Background technique [0002] In high-power solid-state lasers, take the NIF large-scale laser facility in the United States as an example. In order to create the extreme high-temperature and high-pressure environment required for fusion to occur in the laboratory, this type of device consists of hundreds of high-energy solid-state lasers passing through an optical path of hundreds of meters. After that, it is accurately shot at the target ball with a diameter of a few millimeters. The time deviation of each beam of high-energy laser reaching the center of the target is less than 60ps, and the target error is less than 50μm. Such a high precision requirement is guaranteed by thousands of precision optical co...
