Opis

This NATO Advanced Research Workshop on "Inverse Methods in Electro- magnetic Imaging" has come at a time of greatly increased interest in using electromagnetic imaging methods as tools for remote sens- ing, material testing and medical diagnosis. Spurred by a combina- tion of recent advances in sensor and device technology spanning the entire m-to-sub-mm wavelengths, the infra-red, optical, ultraviolet and x-ray regions of the electromagnetic spectrum, the rapid devel- opment of radar polarimetry including the deployment of active/pas- sive sensors on spacecraft platforms, it has become evident that these advanced imaging techniques can only then become useful when supported by well-developed inverse scattering theories for proper consistent and efficient data interpretation. However, these data interpretative techniques, which are urgently needed in several mil- itary and civilian areas, are in many aspects not yet completely de- veloped. Thus, the main purpose of this NATO-ARW-IMEI-1983 was to bring together internationally renowned key experts of this new scientific discipline of Inverse Methods in Electromagnetic Imaging and have them prepare well-written overviews, treatises on new areas, papers on special topics; have them deliberate on still unre- sovled problems in worki~g discussion groups, and then report back on their important findings to the entire NATO Scientific Community in dealing with these exciting current developments.

`This text is probably unequalled as a source of information and references on this subject.'
Optics News (September 1986)
`These collected papers are a valuable source and an excellent introduction to the diversity and complexity of the inversion problem... These two volumes are certainly worth inclusion in the technical side of any remote sensing library...'
