提高光电编码器分辨率的位置细分方法的研究

Study on Subdivision Method for Enhancing the Resolution of Photoencoder

本文提出一种实用可行的光电码盘分辨率的位置细分方法——幅值细分方法，从原理上进行了深入的分析，并设计了硬件电路，同时采用软件算法解决了细分中存在的随机干扰和非线性补偿问题。这种方法具有实时、细分数高且任意可调的特点。

This paper gives a practical subdivision method for photoencoders signal-peak-subdivision. An algorithm has been presented to resolve the random disturbance and nonlinearity. This subdivision method has real-time property and high-subdividing number.
