Abstract
Holographic interferometry, a new technique for measuring small displacements, is discussed. Application is made to the measure of surface displacements of strained bodies in two specific examples. The curvature of one face of a statically bent bar was examined in detail and compared with the three-dimensional elastic solution. In the second example, the radial-displacement field was measured in the area of the leading edge of a longitudinal compressional stress wave propagating through a bar.
