  • Patent number: 6097528
    Abstract: A microscanner composed of a semiconductor wafer, having formed as a part thereof a cantilevered portion and having mounted thereon at least one laser diode. The cantilevered portion has electrically interfaced thereto a plurality of interconnects capable of delivering varying voltages. The cantilevered portion is deflected in response to the varying voltages and therefore produces a scanning action about an "x" axis, a "y" axis, or an "x" and "y" axis dependent upon the external varying voltage applied thereto and the design of the cantilevered portion. This scanning action operates to scan the light emitted by the at least one laser diode. The microscanner operates to generate a resultant integrated scanned image. This image can be implemented as either a virtual image display or a projected image display.
