SPIE published "Advances in time-of-flight and time-correlated single-photon-counting devices" article by Daniel Durini (Fraunhofer) and Franco Zappa (Politecnico di Milano). The article mostly lists the achievements made as a part of the European Commission's MiSPiA (Microelectronic Single-Photon 3D Imaging Arrays for low-light high-speed Safety and Security Applications) project. For instance, SPAD-based imager with 30um pixels with 12 counts per second (cps) at room temperature and 5V of excess bias over the breakdown voltage.
Correction: The 30um relates to SPAD active area. The pixel size is 100um or more. Thanks to LP for correction!
