Theoretical analysis and experimental result of a displacement measuring system using grating Doppler effect
This paper discusses a new method for measuring displacement using grating Doppler effect. The measuring principle is analyzed theoretically As a result, the measuring formula and the phase relationship between the recieved beat signals have been derived. The experimental results show that this system gives good signals with high signal-to-noise ratio and can be easily used in precision measurements.
