Embodiment Construction

[0032] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0033] Such as figure 1 As shown, the three-point passive support device for the deformation decoupling of the ultra-thin active mirror in this embodiment includes a support frame plate 1 and a guide rail slider assembly 8; the guide rail slider assembly 8 is arranged radially along the support frame plate 1. This embodiment It includes 3 guide rail and slider assemblies 8, and the 3 guide rail and slider assemblies 8 are evenly distributed.

[0034] Such as figure 2 As shown, each guide rail slider assembly 8 is mainly composed of a support member 2, a fisheye bearing 3, a transition seat 4, a slider 5, a guide rail 6, a spring assembly 7, and the like. The guide rails 6 are arranged radially along the support frame plate 1, and the three guide rails 6 are evenly distributed to form an angle of 120 degrees with each other. The slider 5 is arranged on the guide...

Abstract

The invention relates to a three point passive support device design, in particular to a three point passive support device adapting to ultrathin dynamic mirror deformation decoupling. The three pointpassive support device adapting to ultrathin dynamic mirror deformation decoupling comprises a support frame plate and three guide rail sliding block assemblies fixed to the support frame plate; allthe guide rail sliding block assemblies are radially arranged on the support frame plate, the guide rail sliding block assemblies comprises spring assemblies, guide rails, sliding blocks capable of sliding along the guide rails, fisheye bearings fixed to the upper surface of the sliding blocks and support pieces fixed to the inner holes of the fisheye bearings; the curvature radius of the end partof the support pieces is equal to the curvature radius of an ultrathin mirror, and the support pieces are used for fixing the ultrathin mirror; and the spring assemblies are connected with the sliding blocks, and the spring assemblies are capable of adjusting the positions of the sliding blocks on the guide rails. The technical problems such as support positioning of a reflecting mirror and deformation decoupling when the PZT being actuated are solved, and the three point passive support device adapting to ultrathin dynamic mirror deformation decoupling has great application prospects.

Description

Technical field [0001] The invention relates to a three-point passive support device design, in particular to a three-point passive support device adapted to the deformation decoupling of an ultra-thin active mirror. Background technique [0002] Modern optical technology puts forward higher and higher requirements for the lightweight of optical systems. The main reflector is one of the most important components in the optical system, and its weight also plays a key role in the entire optical instrument. The traditional method is to reduce the weight by machining or ultrasonic drilling on the back or side of the mirror. After that, through the continuous use of new materials and new processes, the lightweight of optical components was effectively realized. However, for the mirrors of large-aperture optical systems, especially telescopes for outer space exploration, high processing accuracy and sufficient rigidity are required, so there are great difficulties in lightweight desig...
