Abstract
PURPOSE:To obtain a device which is compact, is stable, and does not require precise adjustment by providing an optical deflector and a condenser lens on the same base plate, forming a luminescent spot at the exit end face of its waveguide or near the same and scanning the same. CONSTITUTION:A luminescent spot scanning element is formed on a base plate 1, and a prism coupler 3, a comb-tooth shape electrode 6 and a thin film lens 9 are provided to a waveguide 2. Laser parallel luminous fluxes 4 are conducted as luminous fluxes 5 through a prism coupler 3 into the waveguide 2. The luminous fluxes 5 are deflected by the diffraction effect caused by the ultrasonic surface elastic waves 7 which are excited by the comb-tooth shape electrode 6 provided in part of the waveguide 2. Further, the deflected luminous fluxes 8 are so condensed by the lens 9 as to form a luminescent spot 11 on the end face 10 of the thin film waveguide. Since in this way the optical deflector and the condenser lens are provided on the same base plate, and scanning is accomplished by forming the luminescent spot at the exit end face of the waveguide of near the same, the compact and stable device is obtained.
