摘要
本文着重从理论上叙述了像全息散斑法测量物体三维位移的原理及三个位移量分离的方法,推出了三个位移分量的计算公式。叙述了实验技术,并给出了实验验证结果。
The principle of measuring three-dimensional displacement of a body and the method of separating the three displacement components are theoretically discussed in this paper. The formulas for calculating Three-dimensional displacement are deduced. The experimental technique is described and the results of the test are given as well.
