Paper Abstract

This paper has researched signal processing methods of grating measurement system, and has come out a method to subdivide grating signals based on BP neural network. This measuring method focuses on the special property of the obtained grating signal. The method also decreases the precision requirement of the signal. When the measuring system changes, subdivision models can be altered automatically by software. BP neural networks can subdivide grating signals with few sampling points but high magnitude. This subdivide-method combines software and hardware, has simple structure, does not require complex circuit, and has a strong adaptive system.
