High-precision temporal interferometry from nonlinearly-spaced phase-shifted interferograms through spatial-filtering
Manuel Servin, Moises Padilla, Guillermo Garnica +1
We present a high-precision temporal-spatial phase-demodulation algorithm for phase-shifting interferometry (PSI) affected by random/systematic phase-stepping errors. Laser interfe…
Fourier spectra for nonuniform phase-shifting algorithms based on principal component analysis
Manuel Servin, Moises Padilla, Guillermo Garnica +1
We develop an error-free, nonuniform phase-stepping algorithm (nPSA) based on principal component analysis (PCA). PCA-based algorithms typically give phase-demodulation errors when…
Design of non-uniformly spaced phase-stepped algorithms using their frequency transfer function
Manuel Servin, Moises Padilla, Guillermo Garnica +1
Here we show how to design phase-shifting algorithms (PSAs) for nonuniform phase-shifted fringe patterns using their frequency transfer function (FTF). Assuming that the nonuniform…
Profilometry with digital fringe-projection at the spatial and temporal Nyquist frequencies
Moises Padilla, Manuel Servin, Guillermo Garnica
A phase-demodulation method for digital fringe-projection profilometry using the spatial and temporal Nyquist frequencies is presented. It allows us to digitize tridimensional surf…
Temporal-multiplexing interferometry applied to co-phased profilometry
Manuel Servin, Moises Padilla, Guillermo Garnica
Fringe-projection profilometry with 1 camera and 1 fringe-projector is a well-known and widely used technique in optical metrology. Spatial-frequency multiplexing interferometry wi…
Synthesis of multi-wavelength temporal phase-shifting algorithms optimized for high signal-to-noise ratio and high detuning robustness using the frequency transfer function
Manuel Servin, Moises Padilla, Guillermo Garnica
Synthesis of single-wavelength temporal phase-shifting algorithms (PSA) for interferometry is well-known and firmly based on the frequency transfer function (FTF) paradigm. Here we…
