<p>Electro-optical Scanner comprising an optical waveguide (41) and an acoustic waveguide (42), arranged on a transparent substrate (40) and being colinear with respect to each other, for deflecting light waves out from the optical waveguide (41) by colinear acousto-optic interaction of the light waves (44) with a short surface acoustic wave traveling diffraction grating (43) propagating in the acoustic waveguide (42). The short traveling diffraction grating (43) is generated by a wide band transducer. Different applications of the electro-optical scanner are possible. <IMAGE></p> |
