4. Shedding New Light on Early Caries Detection

   Explore Article The Canadian Dental Association (Jan 8 2009) Dentistry

   Dental caries continues to be a common chronic disease among various population groups. Patient care can be improved with detection at the earliest stage. However, current techniques do not have sufficient sensitivity and specificity. We discuss 2 new methods — optical coherence tomography (OCT) and polarized Raman spectroscopy (PRS) — that are potentially useful for early caries detection and monitoring. OCT produces morphologic depth images of near-surface tissue structures with ... (Read Full Article)

   The present invention relates in general to optical interferometric systems, and in particular to scanning optical delay lines of an interferometric system.Interferometric systems are deployed in a wide and growing number of applications. Typically, interferometric systems involve two arms, a beam splitter and a beam combiner. A beam of light incident the beam splitter is divided in two: one partof the beam is directed down each of the arms. The ... (Read Full Article)

   Explore Article Scitation (Aug 12 2008) Tunable Sources

   Quadrature interferometry based on 3×3 fiber couplers could be used to double the effective imaging depth in Swept- Source Optical Coherence Tomography. This is due to its ability to suppress the complex conjugate artifact naturally. We present theoretical and experimental results for a 3×3 Mach-Zehnder interferometer using a new unbalanced differential optical detection method. The new interferometer provides simultaneous access to complementary phase components of the complex interferometric signal. No ... (Read Full Article)

    Background and Objectives A combined diffuse reflectance (DR) spectroscopy and doppler optical coherence tomography (DOCT) approach may offer a powerful means for assessment of tissue function, and potentially provide a way for earlier cancer detection through non-invasive local blood supply measurements. The goal of the study was to compare a DR-derived blood-content-related index to a measure of local blood supply flow as furnished by DOCT during manipulations with blood circulation ...

    A direct method for the measurement of the optical attenuation coefficient and the scattering anisotropy parameter based on applying the extended Huygens-Fresnel principle to optical coherence tomography images of blood is demonstrated. The images are acquired with a low-power probing beam at the wavelength of 1300 nm. Values of 12.15 mm−1 and 0.95 are found for the total attenuation coefficient and the scattering anisotropy factor, respectively. Also, as a preliminary ... (Read Full Article)
