摘要
详细地讨论了Hartmann波前传感器质心探测的误差来源。主要讨论了光量子起伏、CCD的背景电子噪声引起的质心探测误差,并对采样阈值对Hartmann波前传感器质心探测精度的影响进行了分析,计算结果表明采取阈值的方法对提高质心的探测精度是非常有利的。本文对Hartmann波前传感器的优化设计以及实际操作提供了一定的理论依据。
The following sorting algorithm of the edged data proposed in the paper is used in the designing of the TV tracker for extended target.On the basis of looking for the starting point and taking the nearest range as the adjacent pixel,the algorithm searches in the chaining data structure and reconstructs the sequential data set of the edged data. Two features of the algorithm is that the storage has been saved and the sorting speed is fast.Since the chaining data structure is used,the storage for the original data and the result data has been saved by sharing.The searching speed can be raised by the avoiding of the repeated operating for the data searching.The sorting examples are given in the end of the paper.
