This research proposes a new imaging technique for near real time multispectral acquisition using CCD RGB cameras of
the so called "Degree Of Polarization" (DOP) in polarimetry for future clinical investigation.
The aim of exploiting the DOP as the contrast element is to demonstrate that the elliptical DOP provides more
information characterizing complex medium than the more traditional linear and circular ones. The system considers an
incoherent input white light beam and opportunely calibrated nematic crystals (LCVR), so no mechanical tools are
The particular features of the system indicate it to be the perfect candidate for a new imaging system considering in-vivo
(as well as ex-vivo) non invasive superficial diagnostic for medical application as dermatologic diagnostics, since no
type of sample preparation is necessary, i.e. tissue biopsy, radiation or contrast agent injection.
Thus the biomedical application of this method suggests a simple, direct, fast and also easily exploitable future
employment, as a desirable mean for clinical investigation but also for digital recognition in biometrics.
Further new elements to improve the model of light scattering and matter-light interaction will be acquired, in particular
considering a very complete characterization of the system response using latex microspheres suspension to simulate
turbid media with different concentration.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
