Acoustical Filtering with Holographically Matched Spatial Filters,. The ageing forms of different structures, systems and components vary from each other. In general, the ageing of nuclear power plant mainly includes degradation in ductility and toughness, crack propagation, thickness reduction and pitting, etc. The ageing of structures, systems and components wou

The use of indicator organisms, while certainly not new, is the corner­ stone for much scientific research. In the past two decades, indicator organisms have played increasingly important roles in the deve978-1-4612-8334-8978-1-4612-3752-5

The effects of nonlinearities, sampling rates and pulse duration, coherent sound, and wavelength scaling on the acoustical image are discussed. The problem of three-dimensional visualization of the acoustical image is considered in detail. The third part of this pape

Applying these concepts to an extended object allows us to describe it by a spatial frequency spectrum. Its bandwidth in any particular hologram can be determined from a study of the Fourier transform, which makes it possible to

There is little doubt, however, that given a suitably rapid detection and image presentation system, very considerable diagnostic information can be obtained by this method.

For the geometry and relative intensity levels in the object image to be preserved it appears that the following two conditions are nece
