Photodetector arrays are groupings of integrated photosensor pixels. These arrays measure light particles and convert them into electrical currents via p-n junctions (semiconductor interfaces).
Photodetector arrays can measure light distribution along lines or beams. They can also render images from patterns of light via sensor processes. Examples of photodetector arrays include photodiodes and phototransistors.
Photodetector arrays are used for testing purposes in data communications, broadband and CATV networks. They are also used for monitoring data centre equipment or connections of active optical cables.
In 3D scanning, facial recognition and augmented reality applications, photodetector arrays are used to form images from reflected light particles.
Photodetector arrays are grouped by their detection mechanisms:
