  • Publication number: 20240142307
    Abstract: A full-range imaging method doubles imaging range of conventional techniques by removing mirror images of an imaged object that limit conventional images to a “half-range” and that are caused in part by the loss of phase information in a detected signal. Phase information of the detected signal is reconstructed with an averaging technique based on a modulated phase induced in the detected signal during scanning.

  • Patent number: 8894207
    Abstract: An imaging method is disclosed. An imaging method according to some embodiments can include obtaining a plurality of measurements of an eye for at least one location by scanning optical radiation across the eye; determining a preferred measurement axis from the plurality of measurements; and processing the plurality of measurements to obtain information of the eye.

  • Patent number: 8770753
    Abstract: In accordance with some embodiments, a method of eye examination includes acquiring OCT data with a scan pattern centered on an eye cornea that includes n radial scans repeated r times, c circular scans repeated r times, and n* raster scans where the scan pattern is repeated m times, where each scan includes a A-scans, and where n is an integer that is 0 or greater, r is an integer that is 1 or greater, c is an integer that is 0 or greater, n* is an integer that is 0 or greater, m is an integer that is 1 or greater, and a is an integer greater than 1, the values of n, r, c, n*, and m being chosen to provide OCT data for a target measurement, and processing the OCT data to obtain the target measurement.

  • Patent number: 8405834
    Abstract: In one aspect, the invention relates to a method of acquiring optical coherence tomographic data from a sample. The method includes the steps of scanning a first location on the sample to obtain a first set of optical coherence tomographic data, scanning a second location on the sample to obtain a second set of optical coherence tomographic data, and defining a fiducial position relative to a location on the sample using one of the two sets of optical coherence tomographic data. In one embodiment, the first set of optical coherence tomographic data is survey data. However, in another embodiment the first set of optical coherence tomographic data is sample measurement data.

  • Publication number: 20090054791
    Abstract: Micro-optical imaging is facilitated. According to an example embodiment, a micro-optical probe arrangement includes a GRIN-type lens probe to direct light to and from a specimen. Compensation optics tailored to the probe and aberrations introduced by the lens are located in a light path through the lens, and compensate for the introduced aberrations. A light detector detects light from the specimen, as facilitated by the compensation optics, and generates data characterizing an image of the specimen.
