    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 ...
  • Fast visible and extended nearinfrared multispectral fundus camera 

    Alterini, Tommaso; Díaz Douton, Fernando; Burgos Fernández, Francisco Javier; Gonzalez, Laura; Mateo, Carlos; Vilaseca Ricart, Meritxell (2019-09)
    Article
    Open Access
    We present a multispectral fundus camera that performs fast imaging of the ocular posterior pole in the visible and near-infrared (400 to 1300 nm) wavelengths through 15 spectral bands, using a flashlight source made of ...
  • 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 ...
