Problems solved by technology

The "L"-shaped four-point support reduces the stability and resonance frequency of the mirror; although the fixed support of multi-cylindrical electrodes and non-electrode areas increases the amount of deformation, it has an impact on the surface shape of the mirror and is prone to print-through effects

Abstract

The invention discloses a transverse piezoelectric driving deformation mirror and an assembling method thereof. A transverse shell in the deformation mirror is arranged on a base, a reflecting mirrorand a piezoelectric actuator are bonded and arranged in the inner hole of the transverse shell in a sleeved mode, and an elastic gasket is arranged on the edge of the reflecting mirror. One end face of the elastic gasket is in movable contact with the transverse shell, and the pressure applying device is in threaded sleeve with the inner hole of the transverse shell, and is in contact with the elastic gasket; and an electricity receiving assembly is arranged on the pressure applying device and is connected with the piezoelectric actuator. The method comprises the following steps of s1, bondinga piezoelectric actuator with a reflector; s2 clamping and fastening on the side surface of the reflecting mirror and the upper surface and the lower surface of the edge by using an elastic gasket clamping sleeve, and arranging on a pressure applying device; s3, fixing the pressure applying device in the transverse shell sleeve and applying pressure to an elastic gasket; s4, welding a wire and the electricity receiving assembly together, and installing the electricity receiving assembly on the pressure applying device; s5, transversely fixing the transverse shell sleeve on the base. The device has the advantages of being simple in structure, convenient to manufacture and install and capable of effectively improving the deformation of each electrode.

Description

technical field [0001] The invention belongs to the field of wavefront correction of optical adaptive optics systems, and in particular relates to a transverse piezoelectric-driven deformable mirror and an assembly method thereof, which are used for correcting wavefront aberrations of optical systems such as lasers. Background technique [0002] The widely used transverse piezoelectric deformable mirror is the core device of the adaptive optics system. Its structure includes reflective mirror, bonding layer, piezoelectric ceramic sheet, supporting fixture and so on. These structures have a certain influence on the performance of the deformable mirror, and then affect the practicability of the adaptive system. The performance indicators of deformable mirrors mainly include deformation, resonance frequency, spatial aberration fitting accuracy, stability, etc. [0003] The clamping method of the deformable mirror has an influence on the influence function, the amount of defor...
