An efficient, robust and user-free intensity normalization method for patterns with n frequency-multiplexed phases of both additive and multiplicative types is proposed. For this, the parameter estimation approach by using the least-squares method is

An algorithm to generate ronchigrams of parabolic concave mirrors is proposed. Unlike the conventional direct ray-tracing method, which produces scattered pixels, the proposed algorithm returns regularly sampled images. Thus, the proposed algorithm i

A simple non-iterative algorithm for generalized phase-shifting interferometry is proposed. This algorithm recovers the wrapped phase from two or more interferograms with unknown phase steps between 0 and π rad. The proposal is based on the least sq

Some advances in fringe analysis technology for phase computing are presented. A full scheme for phase evaluation, applicable to automatic applications, is proposed. The proposal consists of: a fringe-pattern normalization method, Fourier fringe-norm

A faster and robust generalized phase-shifting interferometry suitable to automatic real-time applications is presented. The proposal is based on the parameter estimation by the least squares method. The algorithm can retrieve the wrapped phase from

The fringe-pattern normalization method by parameter estimation is used to relieve the critical filter's requirements in the Fourier transform method for phase demodulation. By the normalization procedure, the zero order spectrum is suppressed allowi

A simple and inexpensive optical setup to phase-shifting interferometry is proposed. This optical setup is based on the Twyman-Green Interferometer where the phase shift is induced by the lateral displacement of the point laser source. A theoretical
