    2. Phase-sensitive optical coherence tomography to measure optical aberrations in anterior segment

      Phase-sensitive optical coherence tomography to measure optical aberrations in anterior segment
      Techniques for measuring optical aberrations of the eye are disclosed. An example method comprises positioning the eye in a measurement location adjacent to a measurement arm of an optical coherence tomography (OCT) interferometer apparatus, so that source light from the measurement arm passes into the anterior segment of the eye and detecting an interference pattern, the interference pattern resulting from a combination of light reflected from the eye and light ...

    4. Segmentation in optical coherence tomography imaging

      Segmentation in optical coherence tomography imaging
      A method for improving segmentation in optical coherence tomography imaging. The method comprises obtaining an OCT image of imaged tissue, generating a first feature image for at least a portion of the OCT image, and generating a second feature image for at least the portion of the OCT image, based on either the OCT image or the first feature image, by integrating image data in a first direction across the ...

    5. Reconfigurable optical coherence tomography (OCT) system

      Reconfigurable optical coherence tomography (OCT) system
      An optical coherence tomography (OCT) apparatus includes an optical source module comprising two or more selectable optical sources or an optical source configured to selectively operate in two or more source operating modes, or a combination of both, and further comprises an OCT engine coupled to the optical source module, the OCT engine comprising an OCT interferometer. The OCT apparatus still further includes a mode-switching optics module coupled to the ...

    6. Iris edge detection in Optical Coherence Tomography

      Iris edge detection in Optical Coherence Tomography
      A-lines are obtained from an OCT scan of the eye, some of which pass through the iris and the lens and some of which pass through the lens but not the iris. An interface is detected from the A-lines; at least some of this interface is assumed to correspond to either the anterior or posterior of the iris. For each A-line, a first metric is derived from pixels near the ...

    7. Optical coherence tomography (OCT) imaging surgical target tissue by nonlinear scanning of an eye

      Optical coherence tomography (OCT) imaging surgical target tissue by nonlinear scanning of an eye
      Systems and techniques for laser surgery are described. Scan data may be created by determining a coordinate of the object at a set of points along an arc by the imaging system, wherein the coordinate of the object is a Z coordinate of an object layer. An object shape parameter and position parameter may be determined based on the scan data by a system control module by extracting an amplitude ...

    8. Dual-edge sampling with k-clock to avoid aliasing in optical coherence tomography

      Dual-edge sampling with k-clock to avoid aliasing in optical coherence tomography
      Techniques and apparatus for producing sampled Optical Coherence Tomography (OCT) interference signals without aliasing, based on a swept-source OCT interference signal. An example apparatus comprises a k-clock circuit configured to selectively output a k-clock signal at any of a plurality of k-clock frequencies ranging from a minimum k-clock frequency to a maximum k-clock frequency, and an anti-aliasing filter configured to filter a swept-source OCT interference signal, to produce a filtered ...
