    The effective and non-invasive diagnosis of skin cancer is a hot topic in biophotonics since the current gold standard, a biopsy, is slow and costly. Non-invasive optical techniques such as polarization and multispectral ...
  • A full Stokes imaging polarimeter based on a consumer CMOS camera 

    Peña Gutiérrez, Sara; Ballesta Garcia, Maria; Royo Royo, Santiago (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
    Conference lecture

    En este trabajo se presenta un novedoso sistema confocal de flujometría láser Doppler. Por medio de una técnica de interferometría realimentada, se infiere la frecuencia Doppler relativa a la velocidad con que fluye una ...
  • Hyperspectral eye fundus imaging with extended spectral range towards the near infrared 

    Alterini, Tommaso; Díaz Douton, Fernando; Vilaseca Ricart, Meritxell (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
    Conference report
    Restricted access - publisher's policy
    Eye fundus photography routinely used in clinical practice is restricted to color imaging of the retina. In the last years, hyperspectral imaging has shown to be a powerful tool for the spectral analysis of biological ...
  • Multiorder diffractive lenses with low f-number 

    Pérez Cabré, Elisabet; Millán Garcia-Varela, M. Sagrario; Valverde Sánchez, José (Universidad de Zaragoza (UZA), 2019)
    Conference lecture
    Restricted access - publisher's policy
    Recent liquid crystal on silicon (LCoS) spatial light modulators (SLMs) working on reflection can achieve large phase modulation ranges, permiting the implementation of multiorder diffractive lenses. These lenses are ...
