ABSTRACT:
In an acoustooptic deflection device, a plurality of split light beams are produced from a beam splitter in response to a single incident light beam and projected onto partial deflectors comprising acoustooptic medium blocks and transducers attached to the blocks, respectively. The transducers are supplied from voltage controlled oscillators with carrier signals falling within frequency bands different from one another, respectively, and have different thicknesses to vary input impedances of the respective partial deflectors. Preferably, deflected light beams are propagated from the partial deflectors through an optical system to be converged into a predetermined geometric arrangement. The beam splitter may be a body having a pair of parallel surfaces covered with reflection and semitransparent layers, a diffraction grating, or a fiber grating.
