Integrated adaptive optical wavefront sensing and compensating system

摘要

A wavefront sensing and compensating system for detecting and correcting for distortion in light wavefronts is described in which the wavefront is divided into a plurality of subapertures and light intensified and imaged as spots of light from each subaperture onto a detector array. The individual detector elements of the array form a plurality of electrical signals proportional to the local divergence of the vector gradient field ( NABLA 2 phi ). This NABLA 2 phi signal after interfacing or reconstruction is applied to corrective mirrors which may be of the deformable or membrane type.
