Infrared Illumination for Time-of-Flight Applications

 

 

The 3D capabilities of Time-of-Flight (TOF) cameras open up new opportunities for a number of applications. One of the challenges of TOF systems is due to the high modulation frequency operating condition, which means that all parts (camera, light sources, etc.) need to be high frequency capable; this might create the perception that TOF systems are rather expensive. This document 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.
