Signalverarbeitung für Intelligente Sensorsysteme

Das Fachgebiet Signalverarbeitung für Intelligente Sensorsysteme (SIS) ist am Institut für Informationstechnik der Fakultät für Elektrotechnik und Informationstechnik beheimatet und wurde am 1. Mai 2025 gegründet. Es kooperiert eng mit dem Fraunhofer-Institut für Zerstörungsfreie Prüfverfahren IZFP. Mitarbeitende auf Seite von Fraunhofer und der Universität forschen gemeinsam in der Forschungsgruppe SigMaSense. Außerdem kooperiert das Fachgebiet SIS eng mit dem Fachgebiet für Elektronische Messtechnik und Signalverarbeitung.

 

Das Fachgebiet SIS erforscht Architekturen zur effizienten Erfassung und Verarbeitung von Sensorsignalen. Der Fokus liegt dabei auf der Erfassung relevanter Signalanteile und der sensornahen Auswertung, um Sensorsysteme effizienter, robuster, und universeller zu machen. Neben einem Schwerpunkt auf Ultraschallsignalen können dabei beispielsweise auch Radar, Röntgen oder Thermographie zum Einsatz kommen. Unsere Hauptanwendungen liegen im Bereich der zerstörungsfreien Prüfverfahren, sowie im Monitoring industrieller Prozesse.

Das Fachgebiet SIS erforscht Architekturen zur effizienten Erfassung und Verarbeitung von Sensorsignalen. Der Fokus liegt dabei auf der Erfassung relevanter Signalanteile und der sensornahen Auswertung, um Sensorsysteme effizienter, robuster, und universeller zu machen. Dabei widmen wir uns einer Vielzahl von Modalitäten, unter anderem:

  • Ultraschall (Körperschall, Luftultraschall)

  • Radar (von Bodenradar bis Terahertz)

  • Röntgen (insb. industrielle Röntgen-CT)

  • Thermographie

Unsere Hauptanwendungen liegen im Bereich der zerstörungsfreien Prüfverfahren (ZfP), sowie im Monitoring industrieller Prozesse. Konkrete Aktivitäten umfassen beispielsweise:

  • Optimierte Anregung, Erfassung und Rekonstruktion für mehrkanalige Ultraschallbildgebung

  • KI-basierte Bildrekonstruktion, Klassifikation und Bewertung von ZfP-Daten

  • Large Language Models (LLM): Wissensmanagement und Schnittstellen für qualifizierte Assistenzsysteme

  • Assistierte Handprüfung zur Steigerung von Zuverlässigkeit und intuitiver Bedienbarkeit technischer Systeme

  • Remote-Inspection-Lösungen für ZfP in Zeiten von Fachkräftemangel

  • Akustisches Monitoring von Fertigungsprozessen, insb. Hochgeschwindigkeitslaserstrahlschweißen und Ultraschallschweißen
