ResumoTemporal modulation of light obtained by a diffraction device consisting of an ultrasonic beam and an optical grating has been theoretically described under the hypotheses of diffraction effects not superposed (thick-screen treatment). In comparison with any thin-screen theory considering spatially superposed effects, the present thick-screen treatment is in better agreement with the experimental results.
