ABSTRACT:
A scanning mirror useful in laser projection devices (LPDs) is provided. The scanning mirror is comprised of a substantially planar member having a movable reflective region and a base region coupled together by a split hinge. A foundation is coupled to the base region by at least one piezoelectric element extending therebetween such that movement the piezoelectric element is transferred to the movable reflective region through the split hinge.
