Sánchez Brea, Luis Miguel ; Torcal Milla, Francisco José ; Bernabeu Martínez, Eusebio | The Optical Society Of America | 2007-08-01We present a technique for determining the contrast of an intensity distribution in the presence of additive noise and other effects, such as undesired local amplitude or offset variations. The method is based on the variogram function. It just [...]texto impreso
Álvarez Herrero, Alberto ; Ramos Zapata, Gonzalo ; Monte Muñoz de la Peña, Francisco del ; Levy, David ; Bernabeu Martínez, Eusebio | Elsevier Science SA | 2004-05-01High refractive index TiO_2–SiO_2 thin films were prepared by the sol–gel method and the optical properties were characterized by spectroscopic ellipsometry. The results of the optical analysis were related with the TiO_2–SiO_2 molar ratio of th[...]texto impreso
Pérez Quintián, Fernando ; Alonso Fernández, José ; Atencia Carrizo, Jesús ; Bernabeu Martínez, Eusebio | The Optical Society Of America | 2003-12-01An optical method for generating a reference signal for an incremental displacement measurement system is proposed. We achieved this zero reference signal by comparing two speckle patterns arriving from two symmetric diffusers, which are used as[...]
