We have developed a novel confocal microscopy system, which can perform both axial and lateral scanning at an ultra high speed. A rotary mirror array (RMA) consists of 36 small mirrors deployed on the surface of a round plate with a small tilting angle and a discrete rotational symmetry. When the RMA rotates at a constant speed, the focal point is scanned inside a sample periodically and linearly. We have demonstrated a scanning rate of 2400 lines per second, which can be readily improved to more than 20000 lines per second. Our scheme can also be used in a fast scanning multi-photon microscope.
