  • Publication number: 20230301513
    Abstract: An imaging system for performing a hybrid spiral scan pattern includes a scanner, a scanner controller in communication with the scanner to direct the scanner to perform a hybrid spiral scan pattern, wherein the hybrid spiral scan pattern includes a constant angular velocity (CAV) spiral scan pattern, a constant linear velocity (CLV) spiral scan pattern, and a transition spiral scan pattern. In some cases, the imaging system further includes a light source, and the scanner is positioned to receive light from the light source and direct the light to an object. In some cases, the imaging system further includes at least one position sensor for detecting actual positions of the scanner during the hybrid spiral scan pattern. In some cases, the imaging system further includes an image processor coupled to receive position data detected by the at least one position sensor and produce an image.

  • Patent number: 9936868
    Abstract: A system for obtaining low-angle circumferential optical access to an eye of a subject. The system includes a light source to generate a beam of light; a beam steering mechanism to steer the beam of light a focusing lens to focus the beam of light; and a contact lens to direct the beam of light into the eye of the subject, the contact lens including a tapered reflective surface to direct the beam of light into the eye of the subject.

  • Patent number: 9384582
    Abstract: Methods and computer program products for quantitative three-dimensional (“3D”) image correction in optical coherence tomography. Using the methods and computer program products, index interface (refracting) surfaces from the raw optical coherence tomography (“OCT”) dataset from an OCT system can be segmented. Normal vectors or partial derivatives of the curvature at a refracting surface can be calculated to obtain a refracted image voxel. A new position of each desired refracted image voxel can be iteratively computed. New refracted corrected voxel positions to an even sampling grid can be interpolated to provide corrected image data. In some embodiments, clinical outputs from the corrected image data can be computed.

  • Patent number: 8403481
    Abstract: Methods of reducing motion artifacts in Optical Coherence Tomography (OCT) include scanning a sample with a scan pattern to acquire OCT data at a plurality of data locations. The data locations are distributed in the scan pattern across the sample such that at least some spatially adjacent data locations are acquired non-sequentially in time. A profile of the sample corresponding to a sample surface or an aspect of an internal structure of the sample is estimated responsive the OCT data.
