ABSTRACT
Optical coherence tomography (OCT) has come as a promising optical technique for imaging live tissues with cellular and subcellular r esolutions. e te chnique, ba sed o n lo w-coherence interferometry, is noninvasive and can operate in approximately real time while providing detailed information on tissue microstructure, and has proven successful in a variety of clinical applications. A detailed description of OCT systems and corresponding theory is presented. Applications are discussed, and derivatives of OCT that introduce polarization, phase, and spectral sensitivity are also described.
