  • Infrared Detector Basics (.pdf)
    known in the ancient world and was given the name pyroelectric in 1824 by Brewster, even though the broad application in infrared detectors was introduced in the early 1970s. Nowadays due to its simple but robust construction and its performance the pyroelectric detector is one of the most widely-used
  • Fundamentals of the Infrared Physical Layer
    communication can be established through free space between two dissimilar devices. This document describes the fundamentals of the infrared physical layer, the IrDA standard and selecting the proper discrete emitter and photodiode components for circuit implementation. Fundamentals of the Infrared
