Opt Express 18:24405-11. 2010..Then, through a convolution algorithm of this set of filters the desired symmetric quadrature filter is recovered. Finally, the method is applied to obtain several tunable filters, like four and five-frame algorithms...
- Algorithm for phase extraction from a set of interferograms with arbitrary phase shiftsJ F Mosiño
1Universidad Tecnológica de León, Blvd Universidad Tecnológica 225 San Carlos, Leon, Gto 37670, Mexico
Opt Express 19:4908-23. 2011..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...
