Paper Abstract

Some results obtained with developed high resolution scanning acoustical microscope are shown in the present paper. Created systems are provided with the set of acoustical objectives for working frequencies from 25 MHz to 1 GHz having different apertures of sound beam and different focus distances. Designed and developed system is capable for capturing both bulk acoustical images, as well as the plane images obtained as cuts in desirable section of an object; so, so-called B-scan as well as C-scan are realized. The presence of noise strongly reduces their quality. To solve this problem it is possible to use methods of mathematical processing. The application of this method allows receiving bulk acoustic images with very high resolution. In the present work the application of four such methods in comparison is considered.
