Abstract
An optical scanner including a substrate, a driving component, and an optical reflector is provided. The driving component is disposed on the substrate and has a first hole. The driving component can swing about a first axis by a time-varied magnetic force. The optical reflector has a reflective surface and is disposed in the first hole. The optical reflector can swing about a second axis by a Lorentz force. The first axis is essentially perpendicular to the second axis. The first axis and the second axis are both essentially parallel to the reflective surface.
Claims35
An optical scanner, comprising:
- a substrate;
- a driving component, configured with a first hole and disposed on the substrate for enabling the same to swing about a first axis by a time-varied magnetic force;
- and
- an optical reflector, configured with a reflective surface and disposed in the first hole for enabling the same to swing about a second axis by a Lorentz force;
- wherein, the first axis is essentially perpendicular to the second axis, and the first axis and the second axis are both essentially parallel to the reflective surface.
An optical scanner, comprising:
- a substrate;
- a driving component, disposed on the substrate and configured with a first hole, further comprising:
- a frame, composed of a metal layer and an insulation layer in a manner that the insulation layer being configured with a via hole is disposed on the metal layer;
- and
- a coil circuit, disposed on the insulation layer and surrounding the first hole while electrically connecting with the metal layer through the via hole;
- and
- an optical reflector, disposed in the first hole.
