1. A method of imaging a retina of a user, the method comprising:
generating, by a sensor, a signal indicative of a position of a feature of a user's head relative to an OCT imaging device;
determining, by a control unit, a user specific reference arm adjustment length range for the user within a reference arm adjustment length range of the OCT device based on the signal indicative of the position of the feature of the user's head relative to the OCT imaging device, wherein the user specific reference arm adjustment length range is smaller than the reference arm adjustment length range; and
controlling, by the control unit, a reference arm length adjustment module of the OCT imaging device during an imaging of the retina of the user to vary a reference arm length of the OCT imaging device within the user specific reference arm adjustment length range to identify an imaging reference arm length for which an OCT image detector of the OCT imaging device produces an OCT signal corresponding to the retina of the user.
