We present a high speed time-domain optical coherence tomography (TD-OCT) technology that is capable of imaging 10 frames per second (fps). A duplex scanning optical delay line driven by a 1 kHz sinusoidal function is implemented and characterized. The reference and sample arms in a Michelson interferometer are simultaneously scanned using two identical piezoelectric transducers (PZTs). We adopted sinusoidal function with constant voltages as the input functions to the PZTs. We achieved an A-scanning speed of 6 m/s. This is the highest speed in TD-OCT systems up to now
