1. A method for imaging a whole eye using an optical coherence tomography system, the whole eye comprising an anterior segment anterior to a pupil and a posterior segment posterior to a pupil, the method comprising:

  • rapidly switching focal optics of a sample arm 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 lens 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.
