Opis

In der Optoelektronik werden neue Forschungsergebnisse in rasantem Tempo in technische Entwicklungen und Anwendungen umgesetzt. Die seit 1973 alle zwei Jahre veranstaltete Kongressmesse "Laser Opto-Elektronik" ermoglicht einen Uberblick uber den aktuellen Stand. Das Programm von "Laser " "87 Opto-Elektronik" umfasste - wie seine Vorganger - wieder ein breites Spektrum der Bereiche Technik und Medizin. In Basis-Seminaren wurden physikalische Grundlagen erlautert, Plenarvortrage vermittelten eine Ubersicht uber wichtige Fachgebiete, in Einzelvortragen wurden neue Ergebnisse mitgeteilt. Der vorliegende Band "Laser/Optoelektronik in der Medizin 1987" enthalt die Vortrage des 7. Internationalen Kongresses mit medizinischen Themenschwerpunkte
