DUAL AXIS TRANSDUCER A dual axis transducer assembly comprises a transducer (20), a yoke (24) which mounts the transducer for oscillating movement about a substantially horizontal axis. A turntable (28) mounts the yoke and hence the transducer for oscillating motion about a vertial axis. Separate motors (10) and (12) supply motion to the transducer and control means (84), (86), (88) are employed to control the operation of the motors. |
