Problems solved by technology

[0002] In order to ensure the imaging quality, the surface shape accuracy requirements in the optical system are often high, especially for the surface shape of the mirror; for small-diameter flat mirrors, the surface shape requirements can be guaranteed by using the back edge support method. For large-caliber reflectors, flexible support is currently the main support method. For planar reflectors in the optical system on the moving platform, flexible support can ensure the surface shape requirements, but the flexible support platform requires high rigidity. Otherwise, the deformation of the mounting platform will be transmitted to the flat mirror through the flexible support, and the mounting platform with high rigidity and flexible support means that the load weight and volume will be increased
In the vibration environment, the requirements of the surface error of the plane mirror cannot be guaranteed, and the support method that cannot adapt to the vibration environment

Abstract

The invention relates to a support structure for a plane reflector on a moving platform, which is composed of a flange ring, a pressing block, a sleeve, a top plate, a locking ring, a ball head rod and a linear motor; the back of the plane reflector is supported by means of edge support On the flange ring, the plane reflector is compressed by a plurality of pressing blocks, and the pressing blocks are fixed on the flange ring; the sleeve is fixed on the back of the plane reflector, and the top plate is fixedly connected with the sleeve; one end of the ball head rod is supported On the top plate, the ball head rod is locked by the locking ring, and the other end of the ball head rod is connected with the linear motor, and the linear motor is fixed on the flange ring. The invention is suitable for the support of the plane reflector in the optical instrument on the moving platform.

Description

technical field [0001] The invention relates to a support structure for a plane reflector on a moving platform, specifically, to ensure that the surface shape error of the plane reflector meets the requirements under the vibration and impact environment of the moveable platform. Background technique [0002] In order to ensure the imaging quality, the requirements for surface shape accuracy in the optical system are often high, especially for the surface shape of the mirror; for small-diameter flat mirrors, the surface shape requirements can be guaranteed by using the back edge support method, For large-caliber mirrors, flexible support is currently the main support method. For planar mirrors in the optical system on a moving platform, flexible support can ensure the surface shape requirements, but the flexible support platform requires high rigidity. Otherwise, the deformation of the mounting platform will be transmitted to the flat mirror through the flexible support, and ...
