Silicon Photomultipliers (SiPM)

Technical Documentation

Compared to other photosensor technologies, such as PiN diodes, APDs, and PMTs, SiPMs offer a winning combination of properties. These include high gain, excellent PDE, and fast timing along with the practical advantages associated with solid-state technology: compactness, ruggedness, low bias voltage, and insensitivity to magnetic fields. Each SiPM series combines high photon detection efficiency (PDE) with low dark count rate; and with other varying characteristics that are suited to specific applications.

Introduction to the Silicon Photomultiplier (SiPM)

A complete introduction to Silicon Photomultipliers, their operational principle and key performance metrics.The Silicon Photomultiplier (SiPM) is a sensor that addresses the challenge of sensing, timing and quantifying low-light signals down to the single-photon level. Traditionally the province of the Photomultiplier Tube (PMT), the Silicon Photomultiplier now offers a highly attractive alternative that combines the low-light detection capabilities of the PMT while offering all the benefits of a solid-state sensor.

Depth sensing with precise measurements is a requirement for many applications in today’s markets, including industrial, consumer, and automotive. ON Semiconductor has designed a suite of depth sensing reference designs and evaluation kits to simplify the design process enabling faster development and time−to−market of depth sensing solutions for multiple markets.


How LiDAR can be used for Industrial Range Finding

LiDAR stands for ‘light detection and ranging’ and is a technique for measuring the distance of objects away from a sensing device. The principles used are very similar to RADAR but, with LiDAR, the radio waves are replaced by light – usually laser light. The LiDAR system emits a beam of light that hits a target before being reflected back to a sensor that is located close to the light source.By measuring the time taken for the light to travel, and knowing the constant speed of light, the distance of the target can be calculated with a high degree of accuracy. This is referred to as Time of Flight (ToF).


LiDAR Partners Program: Bringing the Ecosystem Together

The need for automation in factory and industrial settings will continually increase in the coming years, at the same time as the autonomous driving revolution. These applications all require autonomous perception systems, which use a combination of sensors. LiDAR is the only sensor technology capable of providing a high-resolution, accurate 3D point cloud representing a depth map of the system’s surroundings. With an increased interest in these sensors, the amount of funding, research, and development that has gone into commercializing LiDAR with better performance and lower cost has been immense, exceeding a billion dollars to date.
