Title: Special effect filter
Inventor: ISHIKAWA TAKESHI
IPC: G02B5/20
Filed: 1991-10-14
Abstract: PURPOSE:To vary the-extent of special effect in a fitted state by generating an elastic wave with a driving signal and propagating it to a transparent plate. CONSTITUTION:The special effect filter is equipped with a transparent plate 11 made of an elastic body which transmits light, a driving part 13 which generates the driving signal for electric vibration, and a transducer 12 which propagates the elastic wave generated with the driving signal toward the filter part 11A of the transparent plate. Then a pulse voltage is applied between both the terminals of the transducer 12 and then the generated surface acoustic wave is propagated in the propagation direction shown by an arrow 101 in parallel to the length direction of an electrode part, i.e., toward the filter part 11A. Thus, the surface acoustic wave is propagated in the transparent plate 11 and the surface of the transparent plate 11 becomes uneven to form a diffraction grating. Consequently, incident light is spectrally diffracted in the seven colors to obtain spectral effect.
