    摘要: OCT imaging systems are provided for imaging a spherical-type eye including a source having an associated source arm path and a reference arm having an associated reference arm path coupled to the source path. The reference arm path has an associated reference arm path length. A sample is also provided having an associated sample arm path coupled to the source arm and reference arm paths. A lens having a focal power optimized for a diameter of the spherical-type eye is provided along with a reference arm path length adjustment module coupled to the reference arm. The reference arm path length adjustment module is configured to automatically adjust the reference arm path length such that the reference arm path length is based on an eye diameter of the subject.

    摘要: A method for generating a velocity-indicating, tomographic image of a sample in an optical coherence tomography system includes the steps of (a) acquiring cross-correlation data from the interferometer; (b) generating a grayscale image from the cross-correlation data indicative of a depth-dependent positions of scatterers in the sample; (c) processing the cross-correlation data to produce a velocity value and location of a moving scatterer in the sample; (d) assigning a color to the velocity value; and (f) merging the color into the grayscale image, at a point in the grayscale image indicative of the moving scatterer's location, to produce a velocity-indicating, tomographic image. Preferably a first color is assigned for a positive velocity value and a second color is assigned for a negative velocity value.

    摘要: A surgical microscope assembly includes a microscope main objective and microscope imaging optics. The microscope main objective and microscope imaging optics define a viewing beam path that passes from a sample through the microscope main objective and the microscope imaging optics. The assembly includes an optical coherence tomography (OCT) unit having an illumination beam and a collection beam and a beamsplitter between the microscope main objective and the microscope imaging optics. The beamsplitter is configured to direct a portion of light from the microscope main objective to the microscope imaging optics and to direct another portion of light from the microscope main objective to the OCT unit collection beam. The beamsplitter is further configured to direct an illumination beam from the OCT unit to the microscope main objective and to the sample. A beam forming unit is between the OCT unit and the beamsplitter. The beam forming unit is configured to form the illumination beam of the OCT unit so as to generally correspond to a size of the microscope main objective.
