Optical wavefront sensor and optical wavefront sensing method
An optical wavefront sensor comprising a light manipulation device; a detector for detecting light signals having been subjected to the light manipulation device; and a controller coupled to the manipulation device, the controller controlling the manipulation device to function as a lenslet array, each lenslet of the array focussing an incident portion of a wavefront onto the detector. The controller may also control the distance between the detector and the manipulation device. The spatial resolution of Shack-Hartmann sensors can be increased by digital scanning the wavefront with the manipulation device. The wavefront sensing can be dynamic adaptive by setting of parameters of the manipulation device.
