| 摘 要： | 本文提出一种新的应变测量方法。用模压全息光栅作为应变传感器，测量光栅衍射点空间位置的变化量，直接获得应变或应力分量。全息光栅的模压制作，可以大幅度地降低成本。视频技术与微机技术的运用可以自动地获得应变和应力的数值。

| Abstract: | In this peper, a new technique for strain measurement is presented. Using grating as the strain sensor, we can obtain strain and stress components by measuring the change in space of the position of diffracted spots. The cost of the holographic grating by embossing is greatly decreased. By using the video and computer technologies the strain and stress values can be obtained automatically. |
