This paper describes the design of calibration system structure and program. Inductive displacement sensor calibration system based on virtual instrument is established by using LabVIEW8.5. It can complete the measured signal acquisition and calibration. In the measurement process, the inductive displacement sensor is a converter that measures a displacement and converts it into a electrical signal. By calibration, the system can be quickly translated the voltage signal into the original displacement signal. Compared with the traditional manual method, the calibration system has the advantage of simple structure and easy operation，and the visual linear fitting straight line can be obtained.

In this paper, the working principle of the grating measurement system is combined with the Fourier analysis method of Moiré fringe to establish the mathematical model of the grating signal Lissajous figure to know the quality of the grating signal intuitively. The Mathematica numerical analysis software is used to obtain the graphics of the model, and the correctness of the relationship between the parameters of the grating measurement system and the Lissajous figure equation of the grating signal is verified. The influence of the grating pair angle α on the output voltage signal and Lissajous figure of the grating measurement system is studied. The results show that the intensity of the two-phase output electrical signal decreases gradually with the increase of the deviation of the angle α of the grating pair, but the equal-amplitude of the two-phase output electrical signal does not change; Meanwhile, the shape of the grating signal Lissajous figure gradually changes from the ideal circle to the non-ideal ellipse, until a straight line with a strip slope of 135° is formed.
