基于牛顿插值算法的二维 PSD 非线性校正
Two dimensional PSD nonlinear modified Newton interpolation algorithm
摘要
Abstract
In order to improve the position sensitive detector(PSD)measurement accuracy,re-duce the nonlinear error caused by the online data acquisition,a nonlinear compensation algorithm based on Newton interpolation algorithm is proposed.This algorithm uses micro displacement platform and correction device and is based on difference polynomial algorithm.It can increase or decvease the number to save the arithmetic operation,and simplify the computation.Experimen-tal results show that compared with two linear interpolation algorithm and the interpolation error correction data analysis,the nonlinear compensation precision of this algorithm is higher,and the interpolation error is smaller.关键词
