Abstract: We demonstrate a 256 × 256 passive photon counting imager based on hybridization of back-illuminated silicon Geiger-mode avalanche photodiodes to an all-digital CMOS counting chip. Photon ...

Abstract: The intensive development of Single-photon avalanche photodiode (SPAD) based CMOS image sensors (CIS) continues, with rapid progress [1-6]. Yet, due to unestablished quenching operation [5,6 ...

Avalanche, Helix and Faculty Group have launched Fusion, a new blockchain ecosystem aimed at driving real-world adoption through modular infrastructure tailored to specific industries. Built on ...
