High Dynamic Range enhancement in Mueller matrix polarimetry

Mueller matrix (MM) polarimetry is an effective, non-invasive tool for retrieving information from complex media. However, the finite dynamic range of optical detectors poses a significant challenge when measurements involve strong intensity contrasts, where bright regions risk saturation while dark regions suffer from poor signal-to-noise ratio.

Mueller matrix polarimetry of anisotropic chiral media

, 2010
[eng] Esta tesis se centra en el estudio de medios quirales mediante polarimetría de matriz de Mueller. Ópticamente los medios quirales se caracterizan por tener actividad óptica, que se manifiesta en procesos dispersivos con la birefringencia circular o en procesos de absorción mediante el cicroismo circular.
