Paper Abstract

The basic concepts in the application of new methods to interferogram analysis are introduced. Three ideas are underlined: first, way of obtaining decoding of the equations for the analysis of interferograms at arbitrary phase shifts, second, definition of actual values of phase shifts immediately from values of brightness of interferograms and third, method of a volume expansion at measurement of a phase difference of light waves.
