Abstract:
1. A light scanning arrangement, comprising: a) a scan element oscillatable about an axis, and operative for reflecting light incident thereon; b) a movable support having support portions at opposite sides of the axis; c) a pair of torsion hinges spaced apart along the axis and connected between the movable support and the scan element for supporting the scan element for oscillation about the axis, each torsion hinge having a first hinge portion extending linearly generally parallel to the axis at one side thereof, a second hinge portion extending linearly generally parallel to the axis at an opposite side thereof, and an offset portion extending linearly across the axis and connecting the first and second hinge portions; and d) a drive for directly moving the support portions and, in turn, for indirectly oscillating the scan element about the axis to scan the incident light.
