A new simple technique for determining the phase handedness (clockwise or counterclockwise) of vortex optical beams, which does not require implementation of an interferometric arrangement, is introduced. It is shown that both the phase handedness and the modulus of an azimuthal mode index of the beam can be directly and unambiguously determined on the basis of bending of interference fringes in a...
Self-conjugation of the wave front corresponding to a near-field diffraction of a simple primary waveby an aperture has been realized. Such an operation is performed by using a static hologram that is nonlinearly recorded with a standing reference wave. The contouring effect at the self-conjugated reconstruction is demonstrated. This effect is interpreted within the framework of the Young-Rubinowicz...
