Von Kötern, Jägern und Statussymbolennot previously been related to each other. However, the Green’s function developed here suggests a relationship. I will develop an elementary solution, or Green’s function, for a large class of active imaging methods. The Green’s function is an ellipsoid, and active imaging is described in terms of

Hundehaltung in der zweiten Lebenshälftec case of tomography, waves are propagated through the sample between a series of source and receiver locations placed in a plane around the object. These locations are chosen such that the rays pass through as large a fraction of the object plane as possible, and to conform to any requirements for

Most of ferrites used in such devices are single crystals. Of course it is impossible to grow an ideal crystal: the real ones have defects

Auf den Punkt und zwischen den Zeilenperresolved image” means an image whose resolution is not limited by diffraction and can be finer than a wavelength. In principle, the resolution can be improved up to the pixel spacing of the restored image. This method is composed of two stages.

We observe phonon images showing a new stucture in addition to the well known “focusing”-patterns which can be explained as specular reflection at the back of the silicon crystal. Between the two ridges of the slow transverse (ST) pho
