This paper reports on a novel range camera employing Single Photon Avalanche Diodes for Time-of-Flight imaging applications. The architecture of an active pixel containing a single photon detector and the relative read-out channel is presented together with experimental results of a 64-pixel linear array. The sensor array, fabricated with a standard high-voltage 0.8-μm CMOS technology, exhibits a range accuracy of better than ± 3cm in the range interval 2m to 5m, without any external averaging operation.

In diesem Artikel wird über eine neuartige Range-Kamera aus Single-Photon-Avalanche-Photodioden berichtet. Die Architektur der Active-Pixel-Elemente wird beschrieben, die sowohl einen Single-Photon-Detektor als auch den entsprechenden Auslesekanal enthalten, zusammen mit experimentellen Ergebnissen zu den Eigenschaften einer 64-Pixel-Linear-Kamera. Das Sensorarray, mittels eines kommerziellen 0,8-μm-CMOS-Prozesses hergestellt, liefert eine Distanzgenauigkeit von besser als ± 3cm innerhalb eines Intervalls von 2 bis zu 5 Metern ohne Mittelwertbildung.
