Abstract: The paper presents a new original technique for accurate reconstructing the wave front phase at interferometry measurements based upon the estimation of the signals? amplitudes. The optical signals? processing is implemented within the Rice statistical model. The required phase of the wave front to be reconstructed is calculated from the geometrical considerations from the calculated undistorted amplitudes values. The paper provides both the mathematical basics of the technique and the results of its testing by means of both numerical and physical experiments. The proposed technique can be efficiently applied in a wide circle of scientific and technical tasks in numerous ranging and communication systems.
