Acoustical holography
Abstract
One of the methods of acoustical imaging - acoustical holography - is described. After a historical introduction the principles of holography are shown. Further methods of acoustical holography, the method of imaging by means of the liquid surface deformation, the scanning method, and some other methods not so frequently used are described. Optical and acoustical holographies are compared. Finally, the paper deals with the use of acoustical holography in medicine, biology, in nondestructive testing and other scientific and technological branches.
