Abstract

A miniature device for moving a reference plane or point on an axis (l9) in rotational or x-y directions, particularly useful for two dimensional beam scanning. The device consists of a ferromagnetic ring (35) surrounding a magnetic cure (29) which is flexibly mounted and suspended within it. Electric current at various frequencies is supplied to coils (37) wrapped about and mounted within the ring. The core (29) provides a magnetic field within the ring (35) which defines its coordinates with respect to the ring (35) and its coils (37) and interacts with current applied to the coils (37) to produce torque. The flexible mount (27) suspending the core within the coils permits relative movement therebetween in response to the varying current. Motion of the core may be used to position optical elements. In one embodiment, a mirror (13) is attached to the core and a laser beam reflected off the mirror (13) produces a variety of two dimensional scan patterns. The shape of the patterns is determined by selection of the frequencies of current applied to the coils.
