Method and device for scanning light

摘要

A method of scanning a light beam is disclosed. The method comprises scanning the light beam along a first axis and scanning the light beam along a second axis, such that a functional dependence of the scanning along the first axis is substantially a step-wave, and a functional dependence of the scanning along the second axis is other than a step-wave.

主权项

1. A scanning device, comprising:
a micromirror; a rotor, which comprises a magnetic material attached to the micromirror; and a stator assembly, which comprises:
a core having an air gap, which contains at least a portion of the micromirror and the magnetic material; anda coil arrangement comprising a conductive wire wound on the core so as to cause the core to form a magnetic circuit through the air gap in response to an electrical current flowing in the conductive wire, so that the rotor and the micromirror move in response to the magnetic circuit.
