The twin beam vortex interferometer with a phase-conjugating mirror in a rotating reference
frame is analyzed. The circular motion of the interference pattern occurs due to the …

Michelson interferometry is one of the most widely used techniques for accuracy
measurements. Its main characteristic feature is to infer a displacement in one of the arms of …

The rotational Doppler shift of a photon with orbital angular momentum±?? is shown to be
an even multiple of the angular frequency Ω of the reference frame rotation when the photon …

Optical Vortex Interferometer (OVI) is a new type of interferometer which is based on the
regular net of optical vortices. Optical vortices (OV) are the point like phase singularities. The …

In this paper, method for enhancing the measurement capability of an optical vortex
interferometer is proposed. We adapted the techniques used in the carrier frequency …

It is suggested to use a singular beam of unit topological charge in a scheme of vortex
shearing interferometer intended for the observation of isoclinic fringes. In the interference …

A new simple technique for determining the phase handedness (clockwise or
counterclockwise) of vortex optical beams, which does not require implementation of an …

The regular net of optical vortices generated by the interference of three plane waves can be
used for optical measurements. The instrument based on such vortex net is called optical …

Consider the motion of photons within a rotating photon clock. Will light behave as a particle
as it reflects back and forth between two parallel mirrors rotating in a manner similar to the …

Interference of a vortex beam with a reference beam can specify the amount of orbital
angular momentum carried by the beam. In this study, we demonstrate that the vortex beam …
