Optical tomography is a form of computed tomography (CT) that creates a digital volumetric model of an object by reconstructing images made from light transmitted and scattered through an object.
-Optical tomography is used mostly as a form of medical imaging.
-Optical tomography relies on the object under study being at least partially light-transmitting, so it works best on soft tissues; imaging of breast and brain tissue are examples.
The principle OCT is white light or low coherence interferometry. The optical setup typically consists of an interferometer with a low coherence, broad bandwidth light source. Light is split into and recombined from reference and sample arm, respectively.
