ABSTRACT:
Beam deflecting device constructed with an optical waveguide, a pair of transducers for generating acoustic waves in the waveguide, a device for intersecting a first and a second light beam with acoustic waves from mutually different directions and for diffracting the light beams, a driving device for driving the transducers, and a device for effecting change-over between the first light beam and the second light beam.
