阵列探测器的像点亚像素定位精度

The subpixel interpolation accuracy of image spots with array detectors

本文研究阵列探测器的像点亚像素定位精度与内插算法及像斑大小的关系,文中提出一种校正算法误差、提高定位精度的方法.上述分析和论述通过实验证明是正确的.

Using interpolation technique it is possible to determine the image spots position with subpixel accuracy. After a brief introduction to several common used interpolation algorithms, their algorithm errors are investigated based on a Gaussian image spot model. By correcting the algothm error an even higher accuracy can be achieved. Above analyses are well verified by our experiments.
