针对编码器的小型化和高测量精度的技术要求，本文提出了一种新型绝对式矩阵编码器，它具有刻划圈数少，测量精度高等优点。本文主要进行了新型矩阵码盘设计、译码电路设计、精码校准和细分电路设计，应用Matlab 软件进行仿真。实验结果表明，本文中设计的编码器实现了超小化，体积为Φ30 mm×15 mm，经过A/D细分，编码器分辨率达到了24 位，精度达到了0.2″，进一步说明了阐述的编码和译码方法是可行性的。

To satisfy the requirement of encoder miniaturization and high measuring accuracy, a new-style absolute matrix encoder which offered significant advantages over small reticling circles and high precision was presented in the paper, which carried out the design of new-style matrix encoding disc and coding circuit, exact encoding track calibration and the design of fractionizing circuit by studying the photoelectric encoder. The Matlab simulation results prove that the encoding and coding methods are feasible. The test showed that the cubage of encoder was super-small, its resolution can reach 24 bits, and its precision can reach 0.2″ by A/D converter. The feasibility of encoding and coding method was further proved.
