Abstract
A non-symmetrical scanning mirror for a laser scanning system is stiffer at a bottom end than at a top end. The mirror, which is driven from the bottom end, has a relatively high resonant frequency and can thus accelerate quickly and smoothly. The mirror may be wider or thicker at the bottom end or it may be made stiffer by attaching stiffeners to the bottom end.
