Problems solved by technology

When the actuation direction is parallel to the mirror surface, the actuator acts on the edge of the mirror and can only be used to correct specific aberrations such as defocus and astigmatism, so the application in adaptive optics systems is limited.

Abstract

The invention discloses a driving device and a displacement transmitting component. The displacement transmitting component comprises a seat body, a thruster, an elastic piece and an actuator. Specifically, an actuating channel is arranged inside the seat body, the thruster is arranged at a first end inside the actuating channel, a part of the thruster stretches out of the actuating channel, the elastic piece is respectively connected with the thruster and the seat body, the elastic piece has force which often pushes the thruster to move towards the inner portion of the actuating channel, the actuator is arranged inside the actuating channel, and the actuator is contacted with the thruster. According to the displacement transmitting component, the amount of displacement which the thruster transmits to a mirror body can be adjusted quickly and accurately, and precision and rapidity of the displacement transmitting component are improved.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of precision instruments, in particular to a displacement transmission assembly and a driving device with the displacement transmission assembly. Background technique [0002] Deformable mirrors, also known as deformable mirrors, are mainly used in various adaptive optics systems. As a wavefront correction device to correct wavefront errors, they play an extremely important role in adaptive optics systems. One of the important components, the research and development of the deformable mirror is related to the correction ability and correction accuracy of the whole adaptive optics system. [0003] The deformable mirror compensates the wavefront phase distortion by changing its surface shape, which can be divided into two types: continuous surface shape and discrete surface. The advantage of continuous surface deformation mirror is that it can obtain continuous surface shape and high ...
