Abstract -The scanning tomographic acoustic microscope (STAM) is an instrument that utilizes the principles of diffraction tomography and acoustical holography to produce unambiguous subsurface images of structurally complex objects. One of the several techniques to obtain projection data is to rotate the transducer and another, to rotate the specimen. In either case a small
