Symmetrically weighted center of gravity for Shack-Hartmann wavefront sensing on a laser guide star
, 2010 International audiencePhase local gradient measurements in a Shack-Hartmann (SH) wavefront sensor (WFS) are achieved by tracking the displacements of a spot in each sub-aperture. This can be done by comparing the position of its center-ofgravity (COG) to

Highly Efficient Attitude Estimation Algorithm for Star Trackers Using Optimal Image Matching
, 2013 This paper presents a novel attitude estimation algorithm for spacecraft using a star tracker. The algorithm is based on an efficient approach to match the stars of two images optimally on top of each other, hence the name of the algorithm: AIM (Attitude
