Abstract

For the first time the displacement remote measurement was realized in this paper, utilizing laser Doppler Effect. The Doppler shift of differential structure was analyzed theoretically. The system of differential optical-acoustic modulating structure, big aperture collecting backward scattering light, and compensating the losing signal by computer tracking software was designed. The displacement measurement of paper and metal at a distance of 10 meters long has been achieved with an accuracy of 0.4%.
