激光大坝位移实时监测系统研究

Laser Real time Monitoring System of the Dam Displacement

本文研究了激光大坝位移实时监测系统的原理，制作了焦距为１０ ｍ 的菲涅耳波带板，给出了在５０ ｍ 距离上的测量结果。

The principle of laser real time monitoring system of the dam displacement is studied,the Fresnel wave plate that the focal length is 10 m is manufactured and the measurement result with 50 m range is given.
