1. An optical coherence tomography (OCT) system to measure a retina of an eye, the OCT system comprising:
an OCT interferometer comprising, a detector, a light source comprising one or more of light sources configured to generate one or more light beams, and a plurality of optical elements coupled to the light source to direct the one or more light beams to the retina and generate an interference signal at the detector;
a fixation target;
a three-axis translation stage to translate the plurality of optical elements and the fixation target relative to the eye to position of the OCT interferometer and compensate for a refractive error of the eye; and
a processor operatively coupled to the three-axis translation stage to position the plurality of optical elements and the fixation target to compensate for the refractive error of the eye in response to an intensity of the one or more light beams reflected from the retina;
wherein the plurality of optical elements comprises a lens supported with a three axis translation stage, the lens coupled to the three axis translation stage with movement along a fourth axis relative the three axis translation stage to correct the refractive error.
