Abstract
This paper proposes a two-dimensional (2-D) scanning micromirror drive circuit with auto frequency scan function, which solves the problem of complication of manual calibration for the scanning mirror. It can realize the automatic frequency calibration and high-precision control for the two-dimensional scanning micro mirror, which is characterized by high scanning range and high intelligence. Proposed drive circuit has been validated by the experiment results, and the horizontal and vertical swing angles are greater than ±23.6 and ±5.7 degrees respectively when voltage is 5V, which achieves high-resolution position sensing and wide-angle horizontal scanning.
