摘要：
A system includes: a swept laser light source generating laser light having a frequency swept across a frequency bandwidth as a function of time； a sample path directing a first portion of the laser light to an eye as a probe beam and receiving a returned portion of the probe beam from the eye； a reference path passing therethrough a second portion of the laser light, the reference path having a defined optical path length； and a detector receiving the returned portion of the probe beam from the eye and the second portion of the laser light from the reference path, and in response thereto outputting an optical coherence tomography (OCT) output signal having OCT peaks whose relative timing represents the depths of surfaces of structures of the eye, wherein the sample path includes a fiducial generator which produces a fiducial peak in the OCT output signal.
