    Abstract

    A method using the frequency divtion multiplexing technique of the laser speckle’s spatial frequency to record multiple displacement information on a single specklegram is presented. The full-field fringes corresponding to each deformation of an object can be obtained respectively by optical filtering. An example is given and the operating procedure is described briefly.
