Seitliche Ansicht der THz-Lichtfeld Kamera

Lichtfeld-Kameras nehmen sowohl die Intensität, als auch die Richtung des einfallenden Lichtes auf. Dadurch ermöglichen Sie eine dynamische Fokuspunkt-Einstellung und damit die Generierung von 3-D Bildern. Ursprünglich wurde das Konzept der Lichtfeld-Bildgebung im sichtbaren Bereich des Spektrums realisiert. Unser Lehrstuhl ist führend in der Entwicklung von Lichtfeld-Verfahren für das THz Spektrum, wodurch fundamentales Verständnis gefördert und neue Hardware entwickelt wird um das THz Band zu erschließen.

Zurzeit forschen wir an einem THz-Lichtfeld-Kamera Prototypen, der aus einer 3x3 Matrix von Linsen-gekoppelten 1k-Pixel THz CMOS Kameras besteht, integriert auf einem PCB. Der CMOS Kamera Chip wurde auf der International Solid-State Circuits Conference (ISSCC) 2021 präsentiert. Die Abbildung zeigt den Prototypen der Lichtfeld-Kamera. Dieser Prototyp dient als Hardware-Plattform für die Entwicklung von THz-Lichtfeld 3-D Bildgebungsverfahren in Echtzeit.
