  1. An Update on Novel Non-Invasive Approaches for Periodontal Diagnosis

    Explore Article Optical Coherence Tomography News (Mar 20 2010) Dentistry

    An Update on Novel Non-Invasive Approaches for Periodontal Diagnosis Feature Of The Week 3/21/10: Periodontitis is currently diagnosed almost entirely on the basis of its clinical manifestations: signs of gingival inflammation (e.g., redness and swelling), probing depth (PD), and level of periodontal attachment or amount of alveolar bone loss. In fact, alveolar bone and periodontal attachment loss represent the results of the destructive aspects of the host defense mechanisms responding to opportunistic infections by bacteria present in the gingival ...

  2. Signal processing with unequally spaced data in Fourier-domain optical coherence tomography

    Explore Article SPIE Digital Library (Feb 19 2010) Ophthalmology

    Signal processing with unequally spaced data in Fourier-domain optical coherence tomography Different algorithms for performing Fourier transforms with unequally sampled data in wavenumber space for Fourier-domain optical coherence tomography are considered. The efficiency of these algorithms is evaluated from point-spread functions obtained with a swept-source optical coherence tomography system and from computational time. Images of a 4-layer phantom processed with these different algorithms are compared. We show that convolving the data with an optimized Kaiser-Bessel window allowing a small oversampling factor ...

    The invention provides an interferometric system and method for quadrature detection of optical characteristics of a sample. The system includes a Mach-Zehnder interferometer providing a variable optical delay between light collected from the sample and reference light. The Mach-Zehnder interferometer has an output M.times.N coupler with N.gtoreq.3 output ports. Two differential detectors, each having two input ports coupled to a different two of the N output ports of the M.times.N ... (Read Full Article)
