Algorithm for phase extraction from a set of interferograms with arbitrary phase shifts Article uri icon

abstract

  • The generalized analytical quadrature filter from a set of interferograms with arbitrary phase shifts is obtained. Both symmetrical and non symmetrical algorithms for any order are reported. The analytic expression is obtained through the convolution of a set of two-frame algorithms and expressed in terms of the combinatorial theory. Finally, the solution is applied to obtain several generalized tunable quadrature filters. © 2011 Optical Society of America.
