The acoustic microscope, [1, 2], has something in common with the optical and the electron microscope. The wavelength of the acoustic radiation is equal to that of the optical instrument and the image is acquired through scanning as in the SEM. But, the acoustic instrument differs significantly from the conventional instruments in that it can be used to monitor the elastic properties of biological material. That is the phase of the work that we will emphasise in this presentation. It is hardly surprising that we should be sensitive to elastic parameters since the reflectivity of acoustic waves is determined almost completely by the elasticity of the specimen under study.
