Paper Abstract
We present a compact detection head based on a 32x1 array of Single-Photon Avalanche Diodes (SPAD) and associated
electronics for time tagging single photons (photon counting) with 3μs time-resolution, with high photon detection
efficiency (45% at 450nm) and sharp photon-timing resolution (55 ps). The array is composed by 32 "smart" pixels,
working in photon-counting mode, with fully parallel and synchronous acquisition. The array is driven by an FPGA able
to acquire data from the sensor and to upload them to a remote PC via an USB 2.0 link, for real-time continuous
acquisition up to 312.5 kframe/s. The module is bus-powered for convenient use with laptops, and provides also direct
timing outputs from two pixels for time-resolved measurements (photon timing).
