We demonstrate a noninvasive, three-dimensional, depth-resolved imaging of stratified media with a swept source optical coherence tomography (SS-OCT) system at 1064 nm centre wavelength. A swept source laser is used to enable imaging rate of 100 kHz (100,000 A-scans/s). A comparison between SS-OCT and other imaging modalities is also presented. Brief theory, detail instrumentation of the system and signal processing method are described. The system has axial and transverse resolution of 5 and 14 μm in air respectively. The potential and performance of the system was tested, and two- and three-dimensional imaging of different objects like human skin, infrared detection card, leaf, etc. has been presented.
