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)
MicroElectroMechanical Systems for Radio Frequency applications (i.e. RF-MEMS) show very good performance and characteristics. However, their employment within large-scale commercial applications is still limited by issues related to the reliability of such components. In this work we present the Finite Element Method (FEM) modelling and preliminary(More)
INTRODUCTION Time of Flight (TOF) range cameras, besides being used in industrial metrology applications, have also a potential interest in consumer application such as ambient assisted living and gaming. In these fields, the information offered by the sensor can be used to efficiently track the position of objects and people in the camera field of view,(More)
In the last several years, both scientific and industrial community have shown an increasing interest in range imaging due to its potential use in various application domains such as robotics, vehicle safety, gaming, mobile applications as well as many others. Among the diversity of techniques available for range detection, Time-of-Flight (TOF) offers(More)
This paper reports on characterization results of a single-photon avalanche diode (SPAD) array in standard CMOS 150nm technology. The array is composed by 25 (5 × 5) SPADs, based on p+/n-well active junction along with a retrograde deep n-well guard ring. The square-shaped SPAD has a 10µm active diameter and 15.6µm pitch size, achieving a 39.9% array fill(More)
