Optical coherence tomography

Abstract

Optical coherence tomography (OCT) is widely used in imaging of biological tissues such as eye, skin, and most recently blood vessels. In this chapter, we will give a brief history of OCT and its development, especially during the most recent years. We will also discuss about the physical principles underlying the technology. The spectrum of OCT applications is expanding quickly to include new medical and industrial disciplines. However, in this chapter, we will focus on the applications of OCT in the ophthalmological field, more specifically, in retina. Lastly, we will briefly discuss newer developments in OCT technologies with focus on research topics and future directions of use in ocular diseases.
