Abstract
A high speed, high duty cycle, linear, optical scanning device suitable for optical coherence tomography, optical coherence microscopy and confocal microscopy is presented. For the microscopy applications stable, periodic scanning is achieved by using a rotary mirror array, having a rotational symmetry and mirrors tilted at a small angle with respect to the rotational plane. The rotary mirror array is rotated at a constant speed. For the tomography application periodic modulation of the optical path-length of the reference beam is controlled by the rotation of the rotary mirror array.
