Abstract:
1. An impulse actuated shutter, comprising: a shutter blade, comprising a blade disposed at a first end of a flexure and having an opposite second end fixed so as to constrain the blade to move along a first trajectory and between opposite initial and final blade positions; an actuator, comprising a stator and a stage supported for movement relative to the stator along a second trajectory intersecting at least the initial blade position of the blade trajectory and between opposite initial and final stage positions; and, a mechanism for accelerating the stage along the second trajectory and against the blade such that at least some of the momentum of the stage is imparted to the blade and causes the blade to move away from the stage, along the first trajectory, and from the initial blade position to the final blade position.
