- Converting incident light into an electrical signal
Organizing and summarizing search results for youA photodetector works by converting incident light into an electrical signal. It detects photons and generates a corresponding electrical current or voltage. Most photodetectors convert optical signals into electrical signals that can be further processed or stored. Photodetectors that use semiconductors operate on the electron-hole pair creation upon light irradiation principle.4 Sources - See more
