Abstract
A device projecting images by micro electro-mechanical system (MEMS) technology mirrors includes a base, a rotating seat, a substrate, a reflective mirror, a driver, and a controller. The rotating seat is rotably positioned on the base. The substrate is positioned on the rotating seat. The at least one MEMS reflective mirror is formed on the substrate and configured for rotating in two directions under control of the attached driver and controller to form two-dimensional images in a range.
Claims8
A rapidscan device comprising:
- a base;
- a rotating seat rotably positioned on the base;
- a substrate positioned on the rotating seat;
- a reflective mirror formed on the substrate by a micro electro-mechanical system (MEMS) technology and configured for receiving a light beam and rotating in two directions under control of the MEMS for reflecting the light beam to scan in two directions to form images in a range;
- a driver coupled with the rotating seat;
- and
- a controller in communication with the driver and configured to control the driver to drive the rotating seat to rotate, thus adjusting the range of the images.

A projector, comprising:
- a light source for emitting a light beam;
- a rapidscan device;
- an array of projection lenses;
- and
- a screen arranged along a light path of the light beam;
- wherein the rapidscan device comprises:
- a base;
- a rotating seat rotably positioned on the base;
- a substrate positioned on the rotating seat;
- a reflective mirror formed on the substrate by a micro electro-mechanical system (MEMS) technology and configured for receiving the light beam and rotating in two directions under control of the MEMS for reflecting the light beam to scan in two directions to form images in a range;
- a driver coupled with the rotating seat;
- and
- a controller in communication with the driver and configured to control the driver to drive the rotating seat to rotate, thus adjusting the range of the images.

A rapidscan device comprising:
- a base;
- a rotating seat rotably coupled to the base;
- a substrate coupled to the rotating seat;
- a reflective mirror formed on the substrate and being a micro electro-mechanical system, the reflective mirror configured to rotate in at least two directions;
- a driver coupled to the rotating seat and configured to rotate the rotating seat;
- and
- a controller electronically coupled to the driver and configured to transmit data to the driver to rotate the rotating seat, thereby adapting a range of the image formed in response to the rotation of the mirror.
