Optical coherence tomography system combining two wavelengths
First Claim
1. An optical coherence tomography (OCT) system comprising:
- a first light source configured to emit a first beam having a first wavelength;
a second light source configured to emit a second beam having a second wavelength;
an interferometer wherein the first beam and the second beam are configured to be directed into the interferometer, and further wherein the interferometer comprises;
a reference path, andan interferometer sample path;
a first beam splitter configured to divide, from an output of the interferometer sample path;
the first beam into a first sample path, andthe second beam into a second sample path; and
a second beam splitter configured to combine the first beam and the second beam into a common axis.

Abstract
An optical coherence tomography (OCT) system combining multiple wavelengths is generally described. In an example, the OCT system includes a first light source configured to emit a first beam having a first wavelength. The OCT system further includes a second light source configured to emit a second beam having a second wavelength. The OCT system further includes an interferometer. The first beam and the second beam are configured to be directed into the interferometer. The interferometer includes a reference path and an interferometer sample path. The OCT system further includes a first beam splitter configured to divide, from an output of the interferometer sample path the first beam into a first sample path, and the second beam into a second sample path. The OCT system further includes a second beam splitter configured to combine the first beam and the second beam into a common axis.
