Abstract
Official abstract text for this publication.
Systems and methods for expanding the field-of-view of ophthalmic scanning devices are presented. An ophthalmic scanning device is designed such that the pivot point of the scanning optics is maintained at a fixed location in the pupil while the scanning optics are rotated about the eye to obtain imaging data over an increased field-of-view than can be achieved by the scanning optics alone. The rotation can be achieved using a singular rotational motion of the scanning optics about a rotational axes coincident with the scanning pivot point or can be achieved using a combination of rotational motion with a second motion either rotational or translational to maintain the scanning pivot point at the fixed location. Embodiments related to optical coherence tomography and scanning laser ophthalmoscopy are described.
First claim
Opening claim text (preview).
What is claimed is: 1. An ophthalmic imaging device comprising: a light source for generating a beam of radiation; an optics head housing optics and opto-mechanical components for scanning the beam over transverse positions within the eye about a pivot point substantially coincident with a location in the pupil, said optics head being independently movable with respect to the eye so that the beam enters the pupil at multiple different entry angles to vary the field of view of th…
