It has the advantage of high sensitivity and high response time. In some applications, however, PIN photodiodes cannot match the sensitivity of PMTs, and avalanche photodiodes (APDs) should be considered. They have many advantages like single photon response, high detection efficiency, high gain at low bias voltage and very good timing properties but some of their properties, the dark count rate for example, can be a problem. Road traffic is becoming safer, more efficient, and more autonomous. Photodiode. In this regime, carriers (electrons and holes) excited by absorbed photons are strongly accelerated in the strong internal electric field, so that they can generate secondary carriers. The reason for their use is their linear response of photodiode to a light illumination. Similar to photomultipliers, avalanche photodiodes are used to detect extremely weak light intensities. Avalanche photodiodes allow precise and fast measurements especially when only low signal levels are available in optical communication or distance measurement. Advantages of avalanche photodiode. In APDs, applied reverse bias voltage triggers an avalanche – it ensures that the electron-hole pairs are accelerated. A diode is a two terminal electrical component used to build various electrical and electronic circuits. The technology allows continuous monitoring of the surroundings from within the vehicle and makes sure that the lane is kept and hazards due to obstacles are avoided. A photodiode is a PN-junction diode that consumes light energy to produce electric current.
