ABSTRACT:
In an optical scanning device1, a housing3has a space3ain the inside thereof. A floating rotational plate2is housed in the space3a, and is caused to float and to rotate by a magnetic force. The floating rotational plate2has an optical deflection layer6thereon. A diffraction grating71is formed on the optical deflection layer6on and around the center axis Z of the floating rotational plate2. When a beam of light falls incident on the diffraction grating71in a direction normal to the surface of the optical deflection layer6, the diffraction grating71diffracts the light in a radius direction of the circular-shaped floating rotational plate2. The light is transmitted through optical waveguides20and51to be emitted outside from the housing3. By rotating the small-sized floating rotational plate2at a high speed inside the housing3, it is possible to scan the light at a high speed and with a high resolution.
