摘要：
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.
