Abstract
Official abstract text for this publication.
An OCT system for measuring a retina as part of an eye health monitoring and diagnosis system. The OCT system includes an OCT interferometer, where the interferometer comprises a light source or measurement beam and a scanner for moving the beam on the retina of a patient's eye, and a processor configured to execute instructions to cause the scanner to move the measurement beam on the retina in a scan pattern. The scan pattern is a continuous pattern that includes a plurality of lobes. The measurement beam may be caused to move on the retina by the motion of a mirror that intercepts and redirects the measurement beam. The mirror position may be altered by the application of a drive signal to one or more actuators that respond to the drive signal by rotating the mirror about an axis or axes.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical coherence tomography (OCT) system to measure a retina of an eye, comprising: an OCT interferometer comprising a light source to generate a measurement beam, a scanner for moving the measurement beam on the retina in a scan pattern, a plurality of optical elements, and a detector; and a processor operatively coupled to the scanner and configured to execute instructions to cause the scanner to move the measurement beam on the retina in the scan pa…
