Simulations and laboratory performance results of the weighted Fourier phase slope centroiding algorithm in a Shack-Hartmann sensor
The performance of the "weighted Fourier phase slope" centroiding algorithm at the subpupil image of a Shack-Hartmann wavefront sensor for point-like astronomical guiding sources is explored. This algorithm estimates the image's displacement in the Fourier domain by directly computing the phase slope at several spatial frequencies, without the
