Abstract

Optical coherence tomography (OCT) has been used to study the geometry and internal structure of objects. It is based on a Michelson interferometer with an optical broadband source. This method has to change the optical path length of a reference arm to match with that of a sample arm. However, since its reference mirror must be continuously moved for depth scans, it requires a long time because it is limited by mechanical movement speed. The reported maximum speed for longitudinal scans is 21 m/s using a rotating cube and prism.1
