Multiple degree of freedom adjusting system of large aperture reflector

Abstract

The invention belongs to the technical field of optics technology, and in particular to a multiple degree of freedom adjusting system of a large aperture reflector, aiming at overcoming limited degree of freedom adjustment and insufficient fineness of current reflector adjusting apparatuses and the difficulty of unsuitability to large aperture devices. The system herein includes a main mirror chamber, a U-shaped supporting pedestal, a pedestal, a front and back translation assembly, a left and right translation assembly, an orientation rotation assembly and a pitching rotation assembly. The front and back translation assembly is fixed to the pedestal through a linear guide rail. The left and right translation assembly is fixed to the front and back translation assembly through the linear guide rail. The orientation rotation assembly is fixed to the left and right translation assembly through an arc guide rail. The U-shaped supporting pedestal is fixed to the orientation rotation assembly. The main mirror chamber is disposed on the U-shaped supporting pedestal and is rotary. The pitching rotation assembly includes an overturning coarse tuning assembly which is disposed on one side of the main mirror chamber and is connected to the main mirror chamber.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a multi-degree-of-freedom adjustment system of a large-diameter reflector. Background technique [0002] Large-aperture mirrors are one of the commonly used optical testing equipment in the laboratory. The basic requirements for the adjustment device are easy adjustment and high reliability. As the diameter of the reflector increases, its volume and mass increase geometrically, and the complexity of its adjustment device also increases geometrically. At this time, its operability must be considered and adequate safety measures must be taken. The adjustment device of the small-diameter mirror body is generally simple and practical, but it is difficult to be used for a large-diameter mirror with a relatively large mass and volume. The existing large-aperture mirror adjustment system has very limited adjustment freedom, and there are problems such as large volume and i...
