Abstract

To estimate the centroid of a light intensity distribution is a technique widely used in different fields: motion analysis of moving objects from series of frames(1); tracking systems for laser communication(2); resolution improvement by recentering short-exposures images allowing motion removing(3); and adaptive optics, when the wave-front distortion is estimated from the movement of a series of spots produced by an array of lenslet (Hartman-Shack wave-front sensor)(4).
