Abstract
We have developed a simple, high-speed, high-duty-cycle, linear optical delay line suitable for optical coherence tomography and optical Doppler tomography. Periodic longitudinal scanning is achieved by use of a tilted mirror array rotating at a constant speed. With a typical motor speed of 4000 rpm, our system has demonstrated a 2-mm axial scanning range, a 2400-Hz repetition rate, 94% duty cycle, and less than 0.1% nonlinear errors. Much higher repetition rates can be readily achieved by use of high-speed motors.Keywords
