...In biomedical imaging with optical coherence tomography (OCT), [1] frequency-swept lasers have recently enabled imaging speeds of up to several ten thousand axial scans per second, which is 10 to 50 times faster than standard OCT detection techniques.[2-12] A further increase in the sweep rate is desired, because a broad range of promising applications can be envisioned with fast swept-source 3-D OCT....

...In addition to RIN reduction, the balanced detection provides multiple benefits; it suppresses self-interference noise [11] originating from multiple reflections within the sample and optical components; it also improves the dynamic range and reduces fixed-pattern noise by greatly reducing the strong background signal from the reference light....
