Abstract

Es wird ein Verfahren zum Aufnehmen von Farbbildern und Laser-Doppler-Imaging (LDI) -Signalen eines Objektes (117) mit einem gemeinsamen CMOS-Sensor (107) mit einer Anzahl von Sensorelementen zur Verfügung gestellt. Die Farbbilder werden dadurch erzeugt, dass zum Aufnehmen der Farbbilder Sensorelementen Licht wenigstens einer ersten Wellenlänge (102), einer zweiten Wellenlänge (103) und einer dritten Wellenlänge (104) getrennt zugeführt wird. Zum Aufnehmen der LDI-Signale wird den Sensorelementen Strahlung mit einer vierten Wellenlänge (101) getrennt vom Licht mit der ersten Wellenlänge (102), vom Licht mit der zweiten Wellenlänge (103) und vom Licht mit der dritten Wellenlänge (104) zugeführt.
