Abstract

There is provided herein a method and a device to scramble simultaneously the polarization and the phase of the wavefront of the wavefront of a light beam by using a wavefront sampling method and a device that can change the polarization state and the phase retardation of individual samples of the wavefront of the light beam (102 in Fig. 1). An exemplary method consists of sampling the wavefront of a beam having a certain polarization, changing the polarizatoin state of some samples only, leaving the remaining samples with the same polarization state but inducing instead a phase retardation, thus generating another wavefront with different polarization states and phases on its surface (611). The overall polarization and phase of the resulting wavefront will be randomized with respect to the polarization of the initial beam; that is, the polarization state and the phase will be highly scrambled.
