Abstract

The invention is a conjugate imaging-based multi-deformable mirror sires combined wave front corrector, comprising at least two same wave front correctors and corresponding 4f optical system, where the adjacent wave front correctors are interconnected by the 4f optical system to compose a combined wave front corrector and make each wave front corrector located in the optical conjugate imaging position, i.e. each wave front corrector is placed on the front focal surface and rear focal surface of the 4f optical system in order, the wave front corrector can be a deformable mirror using piezoelectric or electrostrictive ceramic as driver and separately driving continuous mirror surface, or a double-voltage deformable mirror, a deformable mirror made by microelectronic mechanical system (MEMS) technique, etc; the 4f optical system adopts a lens-composed refracting system or a reflecting system composed of off-axis parabolic mirror. And the invention has simple structure, high light energy utilization ratio, and can effectively increase wave front correction travel and provides an easy-to-implement method for improving the wave front correcting effect of the self-adapting optical system by using the existing deformable mirror manufacturing technique.

Description

technical field

[0001] The invention relates to a wavefront corrector for an adaptive optics system, in particular to a conjugate imaging-based multi-deformable mirror series combined wavefront corrector. Background technique

[0002] Wavefront phase correction technology is the core technology in adaptive optics, which can usually be realized by using wavefront correction elements that can change the refractive index or optical path length. The application of wavefront correction technology has expanded from astronomy to laser beam shaping, fundus imaging, fast confocal scanning and other fields. In these fields, the demand for deformation of deformable mirrors has also increased significantly. Among them, the wavefront image in the human eye imaging system The poor P-V value can reach more than 20μm. Therefore, for adaptive systems to achieve good wavefront correction in these applications, the deformation of the wavefront corrector must be large enough.
