Photodetector Arrays

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.


What are photodetector arrays used for?

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.

Types of photodetector arrays

Photodetector arrays are grouped by their detection mechanisms:

  • Photochemical, where deviations in the chemical compositions of materials are detected.
  • Photoemission, where the photons cause the trapped electrons on conduction bands of materials to escape into vacuums or gas chambers.
  • Polarisation, where polarity changes are induced by the photons either from negative to positive or positive to negative.
  • Thermal, where photons generate heat by causing the movement of electrons from high bands to low bands.
