摘要：
An optical coherence tomography (OCT) system including a source of broadband optical radiation and a beamsplitter coupled to the source is provided. The beamsplitter divides the source radiation into a reference path and a sample path. The reference path includes an optical switch to switch the reference path between a first path having a first reference reflection at a first reference optical path length and a second path having a second reference reflection at a second reference optical path length. The system further includes a beam combiner that mixes source radiation reflected from a subject in the sample path with source radiation returned from the first reference reflection and the second reference reflection. A detection system detects a first wavelength dependent interferogram during the first time interval and a second wavelength dependent interferogram during the second time interval. A processor preconditions the first and second wavelength dependent interferograms.
