摘　　要：光栅传感器信号精细分中细分误差较大的问题,提出一种新的精细分设计方法——A/D采样重构法,来实现精细分,该方法构造的函数与其线性函数之间的理论误差最大不超过0.3%,并在实际测量中与传统的正切法相比,可判断该方法能有效的解决了信号输出非线性较大的问题.Aiming at the problem of the lager error in the process of fine points,a new method named A/D sampling reconstruction method is put forward in this paper.The maximum error in theory between the function constructed b A/D sampling reconstruction method and linear function.In practical measurement,compared to traditional tangent method,it can be proved that this method can effectively solve the nonlinear problem of output signal.
