In this work, three different pixels for time-resolved, single-photon imaging are investigated. The pixels include a Single-Photon Avalanche Diode (SPAD), a gating circuit and an analog counter. The presented structures aim at achieving sub-nanosecond gating performance with a reduced number of transistors to enable high resolution imaging with a high fill factor. The pixels have been implemented in a test chip and their photon counting capabilities are here presented.

Abstract
In this work, three different pixels for time-resolved, single-photon imaging are investigated. The pixels include a Single-Photon Avalanche Diode (SPAD), a gating circuit and an analog counter. The presented structures aim at achieving sub-nanosecond gating performance with a reduced number of transistors to enable high resolution imaging with a high fill factor. The pixels have been implemented in a test chip and their photon counting capabilities are here presented.File in questo prodotto:
