We developed a high-speed Time-Domain en face OCT with a KTa1‒xNbxO3 (KTN) optical beam
deflector. A KTN optical beam deflector illuminates large area with fast scanning. In our imaging
system, fast scanning was performed at 200 kHz by the KTN optical beam deflector, while slow scanning
at 800 Hz was simultaneously performed by the galvanometer. In a preliminary experiment, we obtained
en face OCT images of a human fingerprint at 800 fps, which is the fastest speed obtained by a TD-OCT.
Furthermore, a 3D-OCT image was also obtained at 0.2 s by our imaging system.
