Wavelength-stepping algorithm for testing thickness, front and back surfaces of optical plates with high signal-to-noise ratio
Manuel Servin, Gonzalo Paez, Moises Padilla +1
We propose a least-squares phase-stepping algorithm (LS-PSA) consisting of only 14 steps for high-quality optical plate testing. Optical plate testing produces an infinite number o…
Super-resolution far-ultraviolet equivalent-wavelength interferometry combining the phase of several visible-wavelength interferograms
Manuel Servin, Moises Padilla, Guillermo Garnica
A far-ultraviolet (FUV) equivalent-wavelength super-resolution interferometric technique is proposed. This FUV equivalent-wavelength interferometric method combines four demodulate…
Extended depth-range profilometry using the phase-difference and phase-sum of two close-sensitivity projected fringes
Manuel Servin, Moises Padilla, Guillermo Garnica
We propose a high signal-to-noise extended depth-range three-dimensional (3D) profilometer projecting two linear-fringes with close phase-sensitivity. We use temporal phase-shiftin…
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…
Fourier analysis of RGB fringe-projection profilometry and robust phase-demodulation methods against crosstalk distortion
Moises Padilla, Manuel Servin, Guillermo Garnica
In this paper we apply the frequency transfer function (FTF) formalism to analyze the red, green and blue (RGB) phase-shifting fringe-projection profilometry technique. The phase-s…
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…
Fourier phase-demodulation applied to strip-light 360-degrees profilometry of 3D solids; theoretical principles
Manuel Servin, Moises Padilla, Guillermo Garnica
360-degrees digitalization of three-dimensional (3D) solids using a projected light-strip is a well established technique. These profilometers project a light-strip over the solid…
