B-spline basis for adaptive piezoelectric mirror shape reconstruction
(2009)
Conference report
Restricted access - publisher's policyIn this paper we compare RMS fitting error of an experimental wavefront for its Zernike and B-spline approximations. Wavefront shapes are achieved using a commercial piezoelectric deformable mirror. Number of Zernike modes ... -

Fast correction in adaptive optical system using block control
(Universidad de Murcia, 2011)
Conference report
Open AccessWe propose to take advantage of the sparse structure of the control matrix in adaptive optical systems in order to allow the acceleration of the control loop in real time wavefront correction. The idea is using the local ... -

Restricted access - publisher's policyLa perfilometría topográfica de la piel en diferentes escalas permite el análisis cuantitativo de los procedimientos médicos y cosméticos. En particular, el uso de parámetros perfilométricos de superficie en las mediciones ... -
Study of skin cancer lesions through multispectral and 3D techniques
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference report
Restricted access - publisher's policyThe effective and non-invasive diagnosis of skin cancer is a hot topic in biophotonics since the current gold standard, biopsy followed by histological examination, is a slow and costly procedure for the healthcare system. ... -
