Patent ID: 8625104

Claim:
An optical coherence tomography system for imaging a whole eye, the whole eye comprising an anterior segment anterior to a pupil and a posterior segment posterior to a pupil, the system comprising: a sample arm including focal optics that are configured to rapidly switch between at least two scanning modes in from about 1.0 ms to about 1.0 second, wherein the at least two scanning modes comprise an anterior segment scanning mode and a posterior segment scanning mode; wherein the sample arm comprises a fiber input, a collimating lens, a scanning mirror, and an objective lens assembly including optical elements arranged in at least two lens groups; wherein one lens group is in a first position with respect to a second lens group of the objective assembly in the anterior segment scanning mode and in a second position in the posterior segment scanning mode; and wherein the one lens group is translated by a distance equal to a focal length of the lens group in switching between the first position for anterior segment scanning and the second position for posterior segment scanning.
