    Abstract: An actuating device (2; 26; 300) and projection and imaging systems (105; 205) using said actuating device are provided. The actuating device includes at least one actuator arm (16; 31, 33, 35, 39; 52, 54, 56, 58; 62, 64, 66; 302, 308) having a piezoelectric membrane. The actuator arm has a width 20 at least ten times its thickness. The actuating device also includes a moveable element (4; 40; 68 304; 70), connected to the actuator arm, such that actuation of the actuator arm causes movement of the moveable element.

    Abstract: A system (100; 200; 300; 400; 500; 600; 700; 800; 900; 1000; 1100; 1200; 2100; 2200; 2905) deflects a laser beam (104; 204; 304; 404; 504; 604; 704; 804; 904; 1004; 1104; 1204, 1220; 1304; 1620; 2104; 2204; 2903) into a zone. The system has a first actuating device (101; 201; 301; 401; 501; 601; 701; 801; 901; 1001; 1101; 1201; 1601; 2101; 2802) comprising a first reflecting moveable surface arranged to tilt about two or more axes so as to deflect the laser beam to define a projection area about a projection centre. The system also includes a second actuating device (102; 202; 302; 402; 502; 602; 702; 802; 902; 1002; 1102; 1202; 1602; 2102; 2800; 2900; 3000) arranged to direct the laser beam so as to determine a location of the projection centre in the zone. The first actuating device is able to move faster than the second actuating device.
