Z-scan applied to phosphate glasses doped with Er-Yb and silver nanoparticles
C. Wiechers, M. A. Martinez-Gamez, M. A. Vallejo-Hernandez +4
We report on the use of Z-scan technique with a beam composed with two modes, to probe the nonlinear optical properties of phosphate glasses doped with Er-Yr and silv…
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…
General theory for super-sensitive dual-wavelength phase metrology: error-free unwrapping and signal-to-noise ratio
Manuel Servin, Moises Padilla, Guillermo Garnica
From 1971 to 2012 dual-wavelength optical-metrology used only the demodulated low-sensitivity phase-difference of two close-sensitive fringes. Dual-wavelength phase-metrology that…
Systematic afterpulsing-estimation algorithms for gated avalanche photodiodes
Carlos Wiechers, Roberto Ramírez-Alarcón, Oscar R. Muñiz-Sánchez +4
We present a method designed to efficiently extract optical signals from InGaAs avalanche photodiodes (APDs) operated in gated mode. In particular, our method permits an estimation…
Co-Phased 360-Degree Profilometry of Discontinuous Solids with 2-Projectors and 1-Camera
Manuel Servin, Guillermo Garnica, J. M. Padilla
Here we describe a co-phased 360-degree fringe-projection profilometer which uses 2-projectors and 1-camera and can digitize discontinuous solids with diffuse light surface. This i…
