To gather more data, Wax and Song added a measurement called angle-resolved low-coherence interferometry (a/LCI), which uses the angles of the scattered light to gather more information about the ...

optical interferometry with surface plasmons) to characterize the spatial degree of coherence of light beams down to subwavelength scales, with measured coherence lengths as low as ∼330 nm for ...

At the heart of OCT is low-coherence interferometry. An OCT system includes essential components such as a light source, a beamsplitter, reference and sample arms, and a detection system.
