Samenvatting

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.
