ABSTRACT:
An integrated electro-optical package including a laser diode microscanner, and an automatic focus mechanism housed within a housing. The microscanner includes a semiconductor wafer, having formed as a part thereof a cantilevered portion having mounted thereon at least one laser diode. The cantilevered portion having 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 in an "x" and/or "y" direction dependent upon the external varying voltage applied thereto and the design of the cantilevered portion. The automatic focus mechanism includes a single detector or a detector array that measures a reflected light and submits a signal to the display system optics for focus adjustment dependent upon the measurements received.
