摘要： A micro-electro-mechanical actuator consists of a first semiconductor layer comprising a movable element with comb electrodes, a support element with inner and outer comb electrodes and a stationary element with comb electrodes, an electrical insulation layer, and a second semiconductor layer with a cavity to allow out-of-plane rotation of the movable and support elements. The movable element is mounted to the support element by a first pair of torsional hinges whereas the support element is mounted to the stationary element by a second pair of torsional hinges such that the actuator is in gimbaled structure. Inner comb electrodes of the support element interdigitate with comb electrodes of the movable element, and outer comb electrodes of the support element interdigitate with comb electrodes of the stationary element in the same plane defined by the first semiconductor layer to form in-plane comb-drive actuators. The in-plane comb-drive actuator may be controlled to generate two-dimensional oscillation of the movable element about the two axes defined by the torsional hinges. The second semiconductor layer may further comprise comb electrodes which interdigitate vertically with outer comb electrodes of support element to form vertical comb-drive actuators. Combing the in-plane and the vertical comb-drive actuators, the movable element is controllable to perform two-dimensional raster scan motion.

摘要： A scanning projection apparatus for displaying image comprises a light source for generating a light beam, a beam scanner which deflects the light beam to project a two dimensional image field, a modulation means for modulating the intensity of the light beam, and a sensor to detect the scanned light beam. The light source may consist of a plurality of semiconductor lasers and/or solid state lasers to generate light beams with wavelengths of red, green and blue colors aligned into a single light path. The image field is divided into an active image field for displaying image and a dark field in the perimeter of the image field wherein the light beam is switched off to reduce inherent image defects. The sensor is positioned outside the active image field to detect a scan line once per image frame to eliminate image distortion due to phase difference between the actual and the predicted positions of the scanned beam, and to detect both the horizontal and the vertical scanning operations of the beam scanner for safety precaution.

摘要： A laser pointer includes a human-machine interface disposed above the housing for users to control components inside the housing to decide patterns and size of the projecting image. The components consist of a frequency/phase control module, a driving energy control module, a laser beam generating module and a light scanning device. The frequency/phase control module controls the driving energy control module while the driving energy control module controls driving energy of the light scanning device. The size of the image is controlled by change of the amplitude of the light scanning device while the amplitude is changed along with the driving energy. The amplitude may also change along with the driving frequency. When the driving energy is fixed and the driving frequency is close to the resonant frequency, the amplitude increases. On the contrary, the amplitude decreases.
