为了提高位置敏感探测器(PSD)的测量精度,减少其非线性带来的误差,提出了基于牛顿插值算法的非线性补偿插值算法。这种新型算法是通过逐次生成插值多项式的算法,当插值节点增减时,只要增加或减少一项即可,可以节省算术运算的次数,极大地简化了运算。实验结果证明,对比双二次线性插值算法的线性校正数据及插值误差分析,该算法的非线性校正精度更高、插值误差较小。

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.
