Shape memory alloy actuator assembly for optical image stabilisation
An SMA actuator is arranged to tilt the mirror in a zoom camera to effect optical image stabilization. The actuator may comprise four angled-V SMA wires. The actuator may alternatively comprise a gimbal flexure and SMA wires. In this case there may be four SMA wires or two SMA wires and two springs....

| description | An SMA actuator is arranged to tilt the mirror in a zoom camera to effect optical image stabilization. The actuator may comprise four angled-V SMA wires. The actuator may alternatively comprise a gimbal flexure and SMA wires. In this case there may be four SMA wires or two SMA wires and two springs. The SMA wires may be straight wires or wires hooked in a V shape. |
