Vilella Figueras, EvaDiéguez Barrientos, Àngel2014-05-142014-05-142014-05-121094-4087https://hdl.handle.net/2445/54003The silicon photomultiplier (SiPM) is a novel detector technology that has undergone a fast development in the last few years, owing to its single-photon resolution and ultra-fast response time. However, the typical high dark count rates of the sensor may prevent the detection of low intensity radiation fluxes. In this article, the time-gated operation with short active periods in the nanosecond range is proposed as a solution to reduce the number of cells fired due to noise and thus increase the dynamic range. The technique is aimed at application fields that function under a trigger command, such as gated fluorescence lifetime imaging microscopy.6 p.application/pdfeng(c) Optical Society of America, 2014Detectors de radiacióMetall-òxid-semiconductors complementarisOptoelectrònicaDetectors òpticsNuclear countersComplementary metal oxide semiconductorsOptoelectronicsOptical detectorsinfo:eu-repo/semantics/article6412362014-05-14info:eu-repo/semantics/openAccess
