Aufgaben der Materialwirtschaftater search during World I. Shortly thereafter many valid ideas were advanced by workers in many nations on how to produce various kinds of acoustic images. The several generic approaches to acoustic imaging can be categorized into one or the other of three key modalities: pulse-echo imaging, intens

In the process a number of interesting new phenomena have been observed, including reflection phonon imaging [1], refocusing and symmetry doubling in reflection [2], pseudo—surface wave structures in phonon imaging [3], total internal reflection of th

This has provided the impetus for the development of the “marching elliptic methods”.. Such methods generally require (1) the backpropagation of a wave field component and (2) the knowledge of both the wave field and its no

The effects of ultrasonic waves on the light transmission through transparent media, arise from refrative index variations induced by the pressure fluctuation of ultrasounds. These variations may be detected optically by deflection,. diffraction . or interference

Die Deutsche Soziologie im Jahre 1955ables us to obtain 3-D information directly from objects, even for metal or glass objects without regard to the environmental optical conditions. The low image resolution, which is a defect of acoustic images, is overcome by applying neural networks to recognition process. By these reasons, the neur
