Abstract

In this paper, a non-resonant 2D micro optical scanner with extremely large optical scan angle has been reported for wide field of view in a LASER application. Two pairs of permanent magnets are mounted on the Si mirror and supporting gimbal structure, respectively, to generate large tilting angle without a thermal degradation of the driving property. The scanner can be driven in two- axis independently by a rotational magnetic torque using orthogonal oriented external electromagnets. The maximum optical scan-angle of 118 degree has been achieved with applying 120mA to the electromagnet.
