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

Structured light projection is one of the most useful methods for accurate three-dimensional scanning. Video projectors are typically used as the illumination source. However, because video projectors are not designed for structured light systems, so

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

This paper presents a method for introducing carrier fringes in a double-aperture common-path interferometer. By using the Fresnel diffraction theory, we demonstrated that the axial displacement of the first lens of the 4 f optical system involved is

An alternative method for phase retrieval based on spatial and binary non-quadrature amplitude modulation (NQAM) is presented. This proposal is based on the superposition of a probe beam with a reference beam modulated in phase and amplitude (PAM) by

This paper presents a method for introducing carrier fringes in an interferogram based on the interference of first harmonic of two rulings with different periods. The setup is built on a 4f optical system consisting of two apertures in the input pla

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

A simple method to evaluate the focal length of concave mirrors is proposed. The inverse ray-tracing approach of the Ronchi test is used in the measurement stage. The theoretical principles are given and a numerical method for ronchigram processing i
