Patent ID: 7555333

Claim:
Apparatus for display of an image, in regard to a limited region of interest, comprising: (a) a light source, which emits light; (b) a cantilever comprising a fixed end and a free end, the fixed end remaining fixed to a substrate, the substrate having a proximal end that serves as a support for the fixed end of the cantilever and having a distal end configured to include a channel, the free end of the cantilever extending freely relative to the substrate, enabling a portion of the free end to bend and deflect within the channel in regard to the limited region of interest, the bending of the cantilever scanning light onto an image plane to create an image, wherein the cantilever is configured as one of: (i) a waveguide that conveys light from the light source within the cantilever, when scanning the light onto the image plane to create the image; and (ii) a moving carrier for the light source that emits the light, the light source being mounted on the free end of the cantilever and moving when scanning the light emitted by the light source onto the image plane to create the image; (c) an actuator disposed adjacent to the cantilever and being employed for deflecting the cantilever so as to move the free end to scan in a desired motion; (d) a photon detector configured to receive light at a location that is proximate to both the free end of the cantilever and the distal end of the support; and (e) a position sensor employed for detecting a position of the free end of the cantilever, for producing a signal used in controlling the actuator to cause the cantilever to move in the desired motion.
