Abstract

An analysis of a "window" 2D/3D Hilbert transform for reconstruction of the phase distribution of the intensity of a speckle field has been carried out. It is shown that the advantage of these approaches consists in the invariance of a phase map to a change of the position of the kernel of transformation and in a possibility to reconstruct the structure forming elements of the skeleton of an optical field. Within the framework of the approach based on the use of the discrete 2D "window" Hilbert transform, we have demonstrated the feasibility for reconstructing the phase of random 2D objects in real time.
