摘　　要：本文根据零位信号的产生原理,提出了一种基于遗传算法的二维零位光栅编码的设计方法。遗传算法是一种自组织、自适应和自学习的智能型算法,能以有限代价来解决大规模问题的搜索和优化。本文采用格雷码进行编码,并对编码过程进行了计算机模拟。对计算机仿真的结果进行了讨论和评价。According to the principle of generating zero-position signal, the design method of two-dimension zero-position grating code is presented based on genetic algorithm. Genetic algorithm is an intelligent algorithm with the features of self-organized, self-adaptive and self-learning, and can be used to solve the problems of searching and optimization for large-scale problems at limited cost. Gray code is applied in the code design and computer simulation was carried out. Finally, the simulation result is discussed and evaluated.
