抽象的。散斑干涉术是一种测量粗糙表面物体变形的有效方法。该方法不仅可以测量物体的面外变形，还可以测量物体的面内变形。近年来，该方法已被用于高分辨率的三维变形测量。目前已经提出了多种基于散斑干涉的三维测量方法。然而，这些常规方法的灵敏度矩阵中的参数在每个3D中通常并不相同。由于每个方向上的测量不确定度不同，在三维中灵敏度不同的方法不能被用作精确的三维测量方法。本文提出了一种在三维空间中灵敏度相同的方法。在此基础上建立了一套光学系统。提出了一种基于矢量分析的物体任意截面变形检测方法。最后，用新的散斑干涉法测量了机械梁屈曲引起的三维变形。
Abstract. Speckle interferometry is a useful optical deformation measurement method for objects with rough surfaces. This method can measure not only the out-of-plane but also the in-plane deformation of these objects. Recently, the method has been used to measure three-dimensional (3-D) deformations at a high resolution. Many kinds of 3-D measurement methods based on speckle interferometry have already been proposed. However, the parameters in the sensitivity matrices of these conventional methods are not generally the same in each of the 3-D. Methods for which the sensitivity is not the same in the 3-D cannot be employed as an exact 3-D measurement method because the measurement uncertainty is different in each direction. This paper proposes a method where the sensitivity is the same in 3-D. An optical system was set up based on the concept of the proposed method. A method based on vector analysis is also proposed for detecting the deformation in an arbitrary section of the object. Finally, the 3-D deformation from the buckling of a mechanical beam was measured using in new speckle interferometry.
