Abstract: The paper presents a new original technique for the accurate real time measuring of the phase shift between two quasi-harmonic optical signals based upon the estimation of amplitudes of the both initial quasi-harmonic signals and the third signal that is formed by summation the first two ones. The required phase difference is then calculated as an angle of a triangle formed by the reconstructed undistorted signals’ amplitudes values. An important peculiarity of the proposed technique consists in the fact that the phase data are obtained as a result of the amplitude measurements only what significantly decreases the demands to the measuring equipment. For the amplitude values estimation the methods of the Rician data analysis are proposed to be applied. The paper provides both the mathematical substantiation of the technique and its computer simulation results. The elaborated method is meaningful for various applied tasks to be solved in numerous ranging and communication systems.
