Abstract: A motorized head supporting and positioning apparatus is disclosed, such as is useful for eye examination or treatment. The apparatus includes head-receiving supports, which can include a forehead rest and a chinrest, which can be linked by a single arm assembly. A main assembly of the apparatus contains a motor assembly, which can include three motors driven in a coupled manner to guide a head along a three-dimensional path at a speed that is comfortable to the patient. The apparatus can be relatively compact, owing at least in part to a pivoted approximate Z-axis movement along the optical axis. In addition to open-loop operation, the apparatus can be used with a tracking subsystem to achieve closed-loop positioning in real time, as well as to enable the activation of an examination/treatment instrument when the eye is brought within an acceptable tolerance of a desired position.

Abstract: An ophthalmic imaging device for improved ophthalmic imaging including: an optical coherence scanning device, a fundus imaging device: an iris viewer; a motorized chin rest; an internal test target, and a fixation target device wherein the optical coherence scanning device, the ophthalmic scanning device, the iris viewer, and the fixation target device all share at least one common optical element. The optical coherence device preferably employs a Mach-Zehnder interferometer with an all fiber reference path; monitoring and attenuating power within the reference path. The multiple devices are separately and in combination aligned with the eye. The system includes internal and external calibration and improved image formats.
