Robust phase demodulation of interferograms with open or closed fringes.

We present two robust algorithms for fringe pattern analysis with partial-field and closed fringes. The algorithm for partial-field fringe patterns is presented as a refinement method for precomputed coarse phases. Such an algorithm consists of the minimization of a regularized cost function that incorporates an outlier rejection strategy, which causes the algorithm to become robust. On the bas...

Phase demodulation of interferograms with open or closed fringes

Analysis of fringe patterns with partial--field and/or closed fringes is still a challenging problem that requires the development of robust methods. This paper presents a method for fringe pattern analysis with those characteristics. The method is initially introduced as a phase refinement process for computed coarse phases, as those obtained from partial--field patterns with a full-field meth...

Demodulation of Interferograms of Closed Fringes by Zernike Polynomials using a technique of Soft Computing

We present the results about to recover the phase of interferograms of closed fringes by Zernike polynomials using a technique of soft computing, applying genetic algorithms (AG) and using an optimization fitness based with Zernike polynomials, with results very satisfactory.

Path independent demodulation method for single image interferograms with closed fringes within the function space C(2).

In the last few years, works have been published about demodulating Single Fringe Pattern Images (SFPI) with closed fringes. The two best known methods are the regularized phase tracker (RPT), and the two-dimensional Hilbert Transform method (2D-HT). In both cases, the demodulation success depends strongly on the path followed to obtain the expected estimation. Therefore, both RPT and 2D-HT are...

Direct demodulation of closed-fringe interferograms based on active contours.

We demonstrate a method to directly demodulate closed-fringe interferograms using a kind of active contour called a snake. This method can be used to demodulate a single closed-fringe interferogram when its background illumination and/or contrast terms have a spatial frequency similar to the spatial frequency of the equivalent normalized interferogram. Among other cases, this problematic usuall...
