Titel
SPAD-based 3D sensors for high ambient illumination
Abstract
With the possibility of fabricating single-photon avalanche diodes in standard CMOS processes, arrays for range imaging applications have been developed. Proper operation in high ambient illumination environments is one of the major issues of scannerless sensors published so far. In this paper a theoretical study of the direct and indirect working principle regarding high ambient illumination is shown. Further, new concepts based on these principles to reduce the sensitivity to ambient light are presented.
