Abstract

The invention discloses a deformable rapid control integrated reflector device, relating to the precision ray machine structure design technology field and solving the problems that the rapid control reflector technology cannot finish the correction of the lower order aberration and the resonant frequency can be affected. The deformable rapid control integrated reflector device comprises a deformable reflector, first actuators, a support platform, a second actuator, an elastic sleeve, a protection ring, a housing, an electric control base plate and a pedestal; the usage quantity of the first actuators is the same as the way of its layout; the deformable reflector is fixedly bonded with the first actuators to form a deformable mirror; the lower part of the first actuators is adhered on the upper surface of the support platform; the second actuator, the elastic sleeve, and the protection ring are fixed under the support platform and fixed on the pedestal; wiring holes are formed in the pedestal; the electric wires of the first actuators which passes through the center hole of the support platform, the electric wire of the second actuator and the related circuit boards are collected in the pedestal; and then the pedestal is sealed through the electric control base plate. The invention can perform wave-front medium-high-order error correction through face shape control.

Description

technical field [0001] The invention relates to the technical field of precision optical-mechanical structure design, in particular to a reflector structure suitable for telescopes, adaptive optics, laser communication, precise tracking and aiming, and stable optical paths. Background technique [0002] With the development of adaptive optics, wavefront correction technology has been widely used in many fields. Piezoelectric deformable mirror is a commonly used wavefront corrector. By continuously measuring wavefront aberration in real time and using negative feedback The form continuously controls the deformable mirror according to the measured aberration, corrects the surface shape in real time, and realizes the correction of the aberration. It has the advantages of large stroke and high bandwidth. The main performance indicators of the deformable mirror include the effective aperture, the number of actuators, the total deformation, and the driving voltage. In the deform...
