Integrated Dual Swept Source for OCT Medical Imaging

An optical coherence analysis system comprising:

• a first swept source that generates a first optical signal that is tuned over a first spectral scan band;
• a second swept source that generates a second optical signal that is tuned over a second spectral scan band;
• a combiner for combining the first optical signal and the second optical signal for form a combined optical signal;
• an interferometer for dividing the combined optical signal between a reference arm leading to a reference reflector and a sample arm leading to a sample;
• a multi channel k-clock system for detecting the first optical signal and the second optical signal to generate clock signals;
• and
• a detector system for detecting an interference signal generated from the combined optical signal from the reference arm and from the sample arm;
• an analog to digital converter system that samples the interference signal and also receives the clock signals.
