Abstract

Imager topology with sub-ns time gating for 3D distance measurement application and first measurement results of the prototype are presented. The imager has a fully digital operating principle with single-photon avalanche diode detectors and on-chip narrow gating of pixel groups. The prototype detector has 80 × 25 pixels with a fill factor of 34 % in the sensor area. The chip has been fabricated in a 0.35 μm high-voltage process and occupies 5.69 × 5.02 mm2 area.
