  1. Transmissive scanning delay line for optical coherence tomography

    Explore Article PatFT » Page 1 of 1 (Aug 26 2008) Patents

    FIELD OF THE INVENTION The invention refers to the field of path scanning, optical measurements, and more specifically to the field of high resolution optical imaging by means of optical coherence tomography. BACKGROUND OF THE INVENTIONOptical coherence tomography (OCT) is an interferometric imaging technique described, for example, in U.S. Pat. No. 5,975,697. In order to produce OCT scans in the depth direction, the optical path length between a reference beam ... (Read Full Article)

  2. Compact high resolution imaging apparatus

    Explore Article PatFT » Page 1 of 1 (Feb 12 2008) Patents

    An optical coherence tomography (OCT) apparatus includes an optical source, an interferometer generating an object beam and a reference beam, a transverse scanner for scanning an object with said object beam, and a processor for generating an OCT image from an OCT signal returned by said interferometer. At least the optical source, the interferometer, and the scanner are mounted on a common translation stage displaceable towards and away from said ... (Read Full Article)

  3. Optical-coherence tomography, extension to imaging of low coherence interferometry

    Explore Article SPIE Digital Library (Aug 1 2007) Art , Microscopy , Other Non-Medical

    Adrian Gh. Podoleanu, Radu G. Cucu, John A. Rogers et al. Results are presented in using low coherence interferometry in quantifying the reflectivity and imaging of different objects, such as tissue, paintings and fruits. All images have been obtained using en-face flying spot technology. This allows simultaneous generation of optical coherence tomography ... [Proc. SPIE Int. Soc. Opt. Eng. 6785, 67851I (2007)] published Wed Aug 1, 2007. (Read Full Article)

  4. Optical mapping apparatus with optimized OCT configuration

    Explore Article PatFT » Page 1 of 1 (Nov 21 2006) Patents

    OCT apparatus includes an interferometer, having an input beam splitter and a 50/50 output splitter. The splitting ratio of the input splitter may be optimized depending on the source power of light source and on the mismatch of the balanced receiver. The input splitter is a plate beam-splitter to minimize the stray reflected light in the interferometer and allow sequential operation of the apparatus in the OCT or in the ... (Read Full Article)

  5. Apparatus for high resolution imaging of moving organs

    Explore Article PatFT » Page 1 of 1 (Sep 26 2006) Patents

    Apparatus for high resolution imaging of a moving object comprises a source of low coherence light, an optical coherence tomography imaging instrument or a dual channel, optical coherence tomography/confocal imaging instrument, a transverse scanner, an interferometer, depth adjustment means, and interface optics. First and an optional second sensing blocks sense the axial and respectively the transverse position of the object. A splitting element is shared so that the interface optics ... (Read Full Article)

  7. Optical mapping apparatus with adjustable depth resolution and multiple functionality

    Explore Article PatFT » Page 1 of 1 (Aug 3 2004) Microscopy , Ophthalmology , Patents

    The present invention relates to a multiple channel optical mapping apparatus which can deliver one or simultaneously at least two images of different depth resolutions or sequentially, images with different depth resolutions, or a combination of these images, or a single image with adjustable depth resolution. The multiple channels could be either multiple confocal channel and one or two optical coherence tomography channel, or two optical coherence tomography channels, or ... (Read Full Article)
