Quiroga Mellado, Juan Antonio ; Crespo Vázquez, Daniel ; Vargas, Javier ; Gómez Pedrero, José Antonio | Spie-Soc Photo-Optical Instrumentation Engineers | 2006-10We present a high-speed 3-D spatiotemporal shape measurement technique by means of structured light. Current methods use a constant number of images that do not take into account the available temporal continuity of the measured object. That is,[...]texto impreso
Álvarez Fernández-Balbuena, Antonio ; González Montes, Mario ; García Botella, Ángel ; Vázquez Moliní, Daniel | Spie-Soc Photo-Optical Instrumentation Engineers | 2015-02-09Automatic optimization algorithms have been recently introduced as nonimaging optics design techniques. Unlike optimization of imaging systems, nonsequential ray tracing simulations and complex noncentered systems design must be considered, addi[...]texto impreso

Varela Vargas, Alberto J. ; Calvo Padilla, María Luisa | Spie-Soc Photo-Optical Instrumentation Engineers | 1995-04We present a comparative study between two experimental methods to determine the modulation transfer function (MTF) of a hololens system. The two hololenses were previously recorded and tested for filtering pseudocolor. In the first method we us[...]texto impreso
Guibelalde del Castillo, Eduardo ; Calvo Padilla, María Luisa | Spie-Soc Photo-Optical Instrumentation Engineers | 1987-06A new integral equation is presented and solved by a matrix method based on iterative procedures to obtain information about the transmission and reflection of light (scalar field) in inhomogeneous media. The method, which may be applied to a wi[...]texto impreso
Quiroga Mellado, Juan Antonio ; Vargas, Javier ; Terrón López, M. José | Spie-Soc Photo-Optical Instrumentation Engineers | 2007-02A novel calibration method for whole field three-dimensional shape measurement by means of fringe projection is presented. Standard calibration techniques, polynomial- and model-based, have practical limitations such as the difficulty of measuri[...]texto impreso
Quiroga Mellado, Juan Antonio ; Crespo Vázquez, Daniel ; Bernabeu Martínez, Eusebio | Spie-Soc Photo-Optical Instrumentation Engineers | 1999-06In this work, a Fourier transform technique for automatic analysis of moire deflectograms is presented. A squared grating is used to multiplex the information of the deflection in two orthogonal directions in one image. This procedure avoids the[...]texto impreso
Lakshminarayanan, Vasudevan ; Calvo Padilla, María Luisa | Spie-Soc Photo-Optical Instrumentation Engineers | 1991-10A systematic procedure for calculating the general transfer function of a cascaded linear optical system working under the Fresnel regime is presented. The validity of neglecting the quadratic phase factors is also discussed. For the case of inh[...]texto impreso
Vázquez Moliní, Daniel ; González Montes, Mario ; Álvarez Fernández-Balbuena, Antonio ; Bernabeu Martínez, Eusebio | Spie-Soc Photo-Optical Instrumentation Engineers | 2010-12We describe an analytical and numerical method to design and optimize LED (light-emitting diode) collimators. The optimization process is confirmed by optical simulations and experimental measurements of a scaled prototype. The collimator's defi[...]texto impreso
Álvarez Fernández-Balbuena, Antonio ; Vázquez Moliní, Daniel ; Alda, Javier ; Bernabeu Martínez, Eusebio | Spie-Soc Photo-Optical Instrumentation Engineers | 2006-07The flux transfer efficiency of an optical array with spatial integration has been improved by adding a new element at the input surface. The optical characteristics of the input surfaces of the individual units do not affect the spatial integra[...]texto impreso
Canabal Boutureira, Héctor ; Alonso Fernández, José ; Bernabeu Martínez, Eusebio | Spie-Soc Photo-Optical Instrumentation Engineers | 2001-11A deflectometric method for the characterization of optical systems is presented. It is based on the use of a CCD camera and a subpixel resolution algorithm for the measurement of the deflection of a laser beam that propagates through the system[...]texto impreso
Quiroga Mellado, Juan Antonio ; González Moreno, Ricardo ; Alonso Fernández, José ; Bernabeu Martínez, Eusebio | Spie-Soc Photo-Optical Instrumentation Engineers | 2005-02A method to enlarge the dynamic range of a CCD-based laser beam profiler is presented. The method is based on extended-image-range techniques. The algorithm that generates the extended-irradiance-range image is described in detail. An equivalent[...]texto impreso
Quiroga Mellado, Juan Antonio ; Vargas, Javier | Spie-Soc Photo-Optical Instrumentation Engineers | 2008-023-D triangulation measurement systems with a fixed geometrical configuration have practical limitations that make them inappropriate for a wide variety of applications. The reason is that the ratio between the depth recovery error and the latera[...]texto impreso

Antoranz Canales, Pedro ; Miranda Pantoja, José Miguel ; Yebras Rivera, José Manuel | Spie-Soc Photo-Optical Instrumentation Engineers | 2012-07In this work, three strategies for shortening the output pulse of a silicon photomultiplier (SiPM) are reported. The first strategy is passive filtering, where band-pass filtering removes the lowest frequency components in the signal, getting a [...]
