摘要：
The introduction of a pulsed laser in an electronic speckle shearing pattern interferometer enables the measurement of high speed transient deformations. This paper reports on a(computerized system which allows automatic data reduction by introducing carrier fringes through the translation of a divergent lens. The quantitative determination of the phase map due to deformation is carried out by means of the spatial synchronous detection method. Experimental results obtained for a metal plate transiently deformed by an electromagnetic hammer illustrates the advantages of the proposed system.
