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 ...

Increasing the separation angle of the Wollaston prism provides significantly improved sub-centimeter agreement with models.

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.
