High Resolution Scanning Acoustical Microscope

摘要

Some results obtained with developed high resolution scanning acoustical microscope are shown in present paper. 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. Created systems 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. Results of investigation of technical and biological objects are briefly discussed.
