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 driving devices for realizing the control and change of the mirror surface shape, in particular to a boundary temperature control array type wavefront control device and a manufacturing method thereof. Background technique [0002] Deformable mirrors, also known as deformable mirrors, are mainly used in various adaptive optical systems. They are used as wavefront correction devices to correct wavefront errors. They play an extremely important role in adaptive optical systems. One of the important components of the morphing mirror, the research and development of the deformable mirror is related to the correction capability and correction accuracy of the entire adaptive optical system. [0003] The deformable mirror type compensates for wavefront phase distortion by changing its surface shape. It can be divided into two types: continuous surface shape and discrete surface. Continuous surface deformable mirror has...
