Abstract

Algorithms for interpreting (decoding) of interferograms plotted by the finite-element method are considered. Three directional field-building methods are used in them: the (i) complex averaging method, (ii) the projection-dispersion method, and (iii) the spectral method. The efficiency of the algorithms is checked on simulated and real interferograms. [ABSTRACT FROM AUTHOR]
