Since the 1st papers by means of E. N. Leith and J. Upatnieks near to holography seemed in 1961, there was a digital explosion of study job within the box. greater than 500 papers and articles on holo graphy have seemed within the final ten years. Many functions of holo graphy were proposed, and a few of those are starting to input the world of usefulness. one of many functions that looks to carry nice promise is acoustic imaging by way of holography. the 1st papers in this topic seemed in 1966, yet already study task within the box is burgeoning. 3 symposia utterly dedicated to acoustical holography were held and the papers released in booklet shape. The purposeof this ebook is to compile the result of study in acoustical holography, a few of it as but unpublished, less than one hide in order that employees in holography, nondestructive checking out, scientific imaging, underwater imaging, and seismic exploration can make a decision even if this new procedure might be necessary to them.

32) substituted, let us look at each term and work only with the most significant one. The first term amplitude modulates the beam, but does not diffract it. Therefore, this term does not contribute to the image. We can consider the last two terms simultaneously since they are complex conjugates. Let us use the first term which will be seen to be the true image term. It becomes I A 2* A(2n)2 X f Ä. Yll(W I) . 33) where k l = Wl/C l = 2n/A l and k 2 = W2/C 2 = 2n/A 2. Suppose we regroup the terms of Eq.

Note the complete physical separation of the various waves. Chapter 2 24 a b Fig. 8. This hologram (a) and its reconstructed true image (b) demonstrate the power of the Leith-Upatnieks technique. The image is completely separated from the zero-order light and the out-of-focus conjugate image. 25 Holography and These expressions are the equivalents to Eqs. 14), but are in a form suited to illustrating the separation of the diffracted beams. 20) represents a replica of SI (x, y) propagating at the angle CPI.

This energy is being dissipated by the dash pot, but at the instant that y = 0 the potential energy of the spring vanishes and the kinetic energy of the block represents the total energy of the system. 10) where t n is the time at which y = O. 3. 1. The Force Equation Consider the force on a small volume Llx Lly Llz ofliquid such as shown in Fig. 2. Let P(x, y, z) denote the pressure in the liquid at the location (x, y, z). 13) Acoustics 53 6y Fig. 2. An incremental volume of liquid LlxLlyLlz is used in the derivation of equations describing the propagation of sound in liquids.
