Abstract

We present an ultrahigh-speed swept source optical coherence tomography (SS-OCT) system that allows a volume rate of 400 Hz paired with a time domain (TD) subsystem. For the SS-OCT, a 40 MHz swept source is used, while for the TD-OCT, a broadband source. Both systems employ a scanning system that consists of a KTN scanner paired with a galvoscanner. The KTN crystal scans the beam laterally at 100 kHz. This allows B-scan OCT repetition rate, while with the galvoscanner 200 lines are obtained at 400 Hz in the en-face display of both SS-OCT and TD-OCT systems.
