摘要

本文报道了激光散斑位移应变测量系统的原理和适用性，以及该系统在光纤、箔片和标准化试样上取得的一些实际结果。由于试样的易碎性和较小的物理尺寸，所呈现的一些结果不能用光学以外的手段获得。

A laser-optical strain gauge and its application in material testing

In this paper we report on the theory and applicability of a laser speckle shift strain measurement system as well as some practical results obtained with the discussed system from fibers, foils and standardized specimen. Some of the results presented can not be obtained with other than optical means, because of the fragility and the small physical dimensions of the specimen.
