THE MATHEMATICAL FORMULAS AND THEIR PHYSICAL MEANING OF THE OBJECT-HOLOGRAM-IMAGE TRANSFORMS IN ACOUSTICAL HOLOGRAPHY

The object-hologram-image transforms in acoustical holography are presented. The formulas of three transforms with various combination of continuous and discrete character are given, and the corresponding physical meanings are demonstrated. It is indicated that in constrast with continuous hologram the discrete hologram results in appearance of high order images, some formulas applicable to computer simulations are also given.
