4. Experimental validation of an optimized signal processing method to handle non-linearity in swept-source optical coherence tomography

   Explore Article opticsinfobase.org (May 5 2010) Tunable Sources

   We evaluate various signal processing methods to handle the non-linearity in wavenumber space exhibited by most laser sources for swept-source optical coherence tomography. The following methods are compared for the same set of experimental data: non-uniform discrete Fourier transforms with Vandermonde matrix or with Lomb periodogram, resampling with linear interpolation or spline interpolation prior to fast-Fourier transform (FFT), and resampling with convolution prior to FFT. By selecting an optimized Kaiser-Bessel ... (Read Full Article)

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

   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 ...

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

    Explore Article SPIE Digital Library (Feb 19 2010) Ophthalmology

    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 ...
