Es wird ein neuartiger Ansatz für einen elektro-optischen Sensor erforscht, der kleinste Bewegungen und Veränderungen (z. B. Schweißbildung) der Hautoberfläche berührungslos und mit besonders hoher Genauigkeit (< 100 nm) und Bildrate (1 kHz) in einem Bereich von 1 cm2 in Echtzeit abbilden kann. Hierfür wird der Stand der Technik erweitert zur simultanen Beobachtung aller Bildpunkte einer 2D-Bildebene unter Einsatz digitaler Signalverarbeitung und Radartechnik. Im Vordergrund steht die Validierung des Sensorprinzips, zunächst im Labor mit Phantomen, anschließend in medizinischen Studien mit D02-D05 zum Nachweis eines diagnostischen Mehrwerts z. B. zur Erfassung von Stress.
