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 relates to a boundary temperature control array type wavefront control device. The boundary temperature control array type wavefront control device comprises lens (1), a base (2), heat sinks (3) and heating / refrigerating units (4), wherein the lens (1) is arranged on one side of the base (2), and the heat sinks (3) and the heating / refrigerating units (4) are arranged on the other side of the base (2). The boundary temperature control array type wavefront control device can change the surface shape of an optical element in active optics and enhance the correction capability. Besides, after the local heat conduction situation of the heat sinks around the heating / refrigerating units consistent with a wavefront array plane area is changed, the deformation range of different temperature spots or the same temperature spot can be changed. The boundary temperature control array type wavefront control device is simple in structure, high in regulation accuracy and high in response speed.

Description

technical field [0001] The invention relates to the technical field of a driving device for controlling and changing the shape of a mirror surface, in particular to a boundary temperature control array wave front control device and a manufacturing method thereof. 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...
