Abstract
Optical coherence tomography (OCT) has been started from the applications of ophthalmology. Spectral domain OCT (SD-OCT) is proposed as an alternative to the time domain OCT (TD-OCT). SD-OCT based on spectral interference does not require mechanical scanning, and is able to get phase information without any additional signal processing. Using phase information as a contrast engine of OCT, we can also develop a polarization sensitive SD-OCT (PS-SD-OCT) and Doppler OCT. The application of SD-OCT including swept source OCT (SS-OCT) is introduced. Two dimensional and three dimensional in vivo human retinal images are shown.
