Abstract

Figures method is based on the lissajou graph of more fringe photoelectric signal. The waveform generator produce signal of simulation, the signal lissajou graphs and actual collection of signal lissajou graphs fitting to and comparison. Through the goodness-of-fit parameters of judgement, we can determine parameters of actual waveform. Then we can get the photoelectric signal to meet the equation. The final can draw the subdivision error curve. The figures method can be used in the working field, avert the influence of the speed, and has important meaning to the improvement of high precision encoder´s dynamic precision characteristics.
