Methods that include diffraction effects are discussed for the tomographic reconstruction of the complex index of refraction within a soft-scattering object. The methods are Fourier-domain based and are threfore computationally efficient. An importan

Theoretical, algorithmic and experimental results on the use of Rytov's approximation in acoustic tomography are presented. The approximation error is related to the disturbance size and magnitude. A method of phase unwrapping which is based on a com

A general wave equation for sound propagation in a viscoelastic medium is obtained. From this general equation an approximate inhomogeneous wave equation is derived by perturbation methods. Born's and Rytov's approximations are considered. The equati

Computer technology has brought about a revolution in radiology. By combining the computer with X rays it is possible (in principle) to obtain tomographic images of any cross section in the human body. These techniques are now used for medical diagno

The use of optical correlation techniques to monitor fatigue damage in 2024-T3 aluminum alloy is described. Topographical information from the surface of a sheet specimen is recorded holographically and compared with the actual surface by measuring c
