Optical coherence tomography: Technical aspect

Abstract

This chapter describes the state of the art of optical coherence tomography (OCT), a low coherence interferometric imaging technique that provides cross-sectional depth resolved information from the subsurface microstructure of biological tissue. Following a discussion of the basic theory of OCT, an overview of the design aspect and different configuration of OCT in both time and frequency domain is presented. The chapter also includes various functional extensions of OCT and its potential clinical and non-clinical application.
