Abstract
A generalized treatment for the mechanics of ray acoustics, in the intermediate wavelength regime, is systematically developed. The discussion makes extensive use of geometric acoustical solutions (eikonal solutions) in which their frequency dependence is taken into account. One of the results yields the mapping of the acoustic object-to-image fields by means of a transfer matrix for the acoustic propagation. The study is restricted to the case of coherent illumination.
