Abstract
A system and method of wavefront sensing with a Shack-Hartmann wavefront sensor precisely locates focal spots on a detector array, and determines the location of the lenslet array with respect to the detector array.
Claims8
A method of reconstructing a wavefront from gradient data, comprising:
- obtaining gradient data from a Shack-Hartmann wavefront sensor comprising a lenslet array and a plurality of pixels;
- mapping boundaries of each lenslet onto a grid of the pixels;
- and
- numerically calculating the wavefront at a plurality of vertices of said mapped boundaries.
