METHOD OF MEASURING THE EXACT POSITION OF THE ENERGY CENTER OF AN IMAGE SPOT OF A BRIGHT OBJECT ON A PHOTOSENSITIVE DETECTOR

摘要

The detector is a charge transfer detection matrix and the measurement is effected by barycentric calculation. The stages of the method are as follows: Centering the measuring field (30) around the estimated position of the bright object (PI(1); selecting a first group of NS brightest pixels (31); selecting from these NS pixels the NA pixels clustered around the pixel having the maximum level (37); finally performing a barycentric calculation on the only clustered NA pixels (IE) of the measuring field.
