Abstract

Two applications of the diffraction of light by surface acoustic waves (SAW) on reflection from, and transmission through a propagation surface are discussed. In the first half of this paper it is shown that the properties of the diffracted light make this scattering technique an ideal diagnostic tool for investigating surface waves and surface wave devices. Measurements of a number of surface wave propagation parameters both on a free surface and inside interdigital transducers are presented. Also discussed are device applications of this acoustooptic interaction. It is demonstrated that an image can be scanned at Megabit/ sec rates using light scattering from SAW. A versatile signal processor which utilizes the double diffraction of light by surface waves is discussed and examples of convolution, time compression and time inversion are shown.
