Infrared (IR) emitters enable unique capabilities including night vision, depth sensing and 3D imaging. Utilizing radiation that is beyond the visible red part of the spectrum, IR emitters bring expanded functions to everything from surveillance cameras to facial recognition. Here are five interesting things to know about infrared emitters and how they use invisible light.
This white paper focuses on Infrared (IR) illumination for TOF systems using Vertical Cavity Surface Emitting LASERs (VCSELs) and Light Emitting Diodes (LEDs) and shows that LEDs are a feasible and affordable option as IR illuminators.
