Patent ID: 8665450

Claim:
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 to form a combined optical signal; an interferometer for dividing the combined optical signal between a reference arm and a sample arm leading to a sample, the interferometer including a detector system for detecting an interference signal generated from the combined optical signal from the reference arm and from the sample arm, wherein the detector system comprises a first detector for detecting the interference signal resulting from the first optical signal and a second detector for detecting the interference signal resulting from the second optical signal; and a polarization beam splitter for separating the interference signal into components resulting from the first optical signal and the second optical signal for detection by the first detector and the second detector.
