Patent ID: 8348429

Claim:
An optical coherence tomography instrument comprising: first and second oculars for directing light to and receiving light reflected from a pair of eyes of a subject; a light source that outputs light that is directed through the first and second oculars to the subject's eye; an interferometer configured to produce optical interference using light reflected from the subject's eye; and an optical detector disposed so as to detect said optical interference; wherein said instrument is configured to obtain optical coherence tomography scans of eye tissue, and said instrument comprises at least one of: (i) auto-focus lenses configured to focus the instrument based on said detected optical interference; or (ii) an interpupillary distance adjustment configured to facilitate the adjustment of interpupillary distance by the subject while the subject looks through said first and second oculars and a Z positioning module configured to automatically and independently adjust the Z offset of each ocular, thereby adjusting a depth at which each scan is obtained.
