摘要

估计光强分布的质心是一种广泛应用于不同领域的技术:从一系列帧中对运动物体进行运动分析(1);激光通信跟踪系统(2);通过重新进入短曝光图像以消除运动来提高分辨率(3);和自适应光学，当波前畸变是由一系列小透镜(哈特曼-夏克波前传感器)产生的一系列点的运动估计(4)。

Error reduction in centroid estimates using image intensifiers

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).
