Dual wavelength resampling system and method

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, and
• an interferometer sample path;
• a detector configured to compare light from the reference path with light from the interferometer sample path and produce an imaging sample signal based on the comparison;
• and
• a first splitter configured to split light from at least one of the first light source and the second light source, wherein the first splitter is located on a light path between the first light source and the interferometer;
• a first wavelength reference filter having an equal interval frequency comb, wherein the wavelength reference filter is configured to produce a sequential clock waveform from light received from the first splitter;
• and
• a signal processing circuit configured to resample the imaging sample signal based on the sequential clock waveform.
