Shannon information storage in noisy phase-modulated fringes and fringe-data compression by phase-shifting algorithms
Manuel Servin, Moises Padilla
Optical phase-modulated fringe-patterns are usually digitized with XxY pixels and 8 bits/pixel (or higher) gray-levels. The digitized 8 bits/pixel are raw-data bits, not Shannon in…
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…
