Vacuum based devices, such as Photo Multiplier Tubes (PMT) and Micro Channel Plates (MCP), have been for many years the sensors of choice for most applications calling for photon counting and timing (Renker, 2004). While providing very good sensitivity, noise and timing characteristics, these photodetectors feature a number of disadvantages: they are bulky,(More)
Because we are living in a three-dimensional world, the usual intensity map provided by standard digital cameras is often not sufficient to build the sophisticated models required by systems capable of analyzing and interpreting their environment. A three-dimensional (3D) image sensor has great potential for improvement in many areas like ambient-assisted(More)
CMOS Single Photon Avalanche Diode (SPAD) arrays are emerging as appealing solid-state detectors in imaging applications where high sensitivity and timing resolution are required. In this work, a 32x32-pixel array where SPAD digital output is processed in the analog domain in a 12-transistor pixel is presented. A 25m pixel pitch with a remarkable 20.8%(More)
The solution-processability of organic photodetectors allows a straightforward combination with other materials, including inorganic ones, without increasing cost and process complexity significantly compared with conventional crystalline semiconductors. Although the optoelectronic performance of these organic devices does not outmatch their inorganic(More)
The need for decentralized clinical tests together with the concept of time and cost saving are pushing the development of portable, miniaturized, compact biosensors with diagnostic and prognostic purpose. Here, we propose an innovative detection system based on a Single Photon Avalanche Diode (SPAD) with high sensitivity and low noise, crucial features for(More)
