An Optimization Algorithm of 1D Zero-position Grating Code

零位光栅作为长度和角度的测量基准是十分重要的,根据零位脉冲产生原理,提出一种基于遗传算法的零位光栅编码优化设计,是一种自组织、自适应算法,能以较小的代价在较大的空间中寻找最优解。并对求解序列作了计算机模拟,得出了较为满意的结果。

As a reference for the applications of length and angular measurements, zero-position grating is very important. According to the basic theory in generating index pulse, an optimization design method of zero-position grating code is presented based on genetic algorithm, which is an organizable and adaptive algorithm. It can look for optimal results in a wider space at a low cost. A computer simulation is made and a satisfied resolution is given.
