Patent ID: 8690328

Claim:
An ophthalmic optical tomographic imaging device, comprising: a tunable light source to provide a wavelength-scanned beam; an interferometer, in optical communication with the tunable light source, to split the wavelength-scanned beam into a reference beam and an object beam; a collimator, in optical communication with the interferometer, to collimate the object beam; a probe, in optical communication with the collimator, to scan the object beam in a first dimension perpendicular to an optical axis of an eye and in a second dimension perpendicular to the optical axis of an eye, the probe comprising: an objective lens, in optical communication with the collimator, to focus the object beam to a spot within the eye; and a two-axis tilt mirror, disposed in a back focal plane of the objective lens, to tilt the object beam from the collimator so as to scan the spot along at least one of the first dimension and the second dimension; and a detector, in optical communication with the eye, to detect a beat signal caused by interference between the reference beam and at least a portion of the object beam reflected from the eye; and an image signal processing unit, operably coupled to the detector, to generate at least one tomographic image of at least a portion of the eye based on the beat signal.
