Remote Displacement Measurement of Solid Scattering Surface Utilizing Laser Doppler Effect
The remote displacement measurement was realized utilizing laser Doppler effect. The Doppler shift of differential structure was analyzed theoretically. The displacement measurement system of double-beam differential acoustooptic modulating structure, large aperture collection of backward scattering light and real-time compensation of the losing signal by computer tracking software was designed. The displacement measurement of paper and metal at a distance of 10 meters was made with an accuracy of ±0.4%.
