High frequency operation of infrared light sources is rapidly gaining interest for various Time-of-Flight applications in automotive, industrial and consumer segments. Due to the fast switching requirements of these applications, mostly Vertical Surface Emitting LASERS (VCSELs) are being considered. VCSEL technology however also comes with its drawbacks including mass volume availability, required eye-safety measures and high cost. Lumileds has demonstrated LUXEON IR Domed and LUXEON IR Compact LEDs can be an ideal alternative to VCSEL technology for Time-of-Flight applications operating up to 40 MHz.

To demonstrate this, engineering teams from Lumileds and Melexis have developed an evaluation kit that allow our customers to operate the LUXEON IR LEDs to high frequencies up to 40MHz. The intrinsic properties of the LUXEON IR LEDs result in a clean and repeatable response curve required for Time-of-Flight operations.

White Paper - Infrared Illumination for Time-of-Flight Applications

Due to the 3D capabilities of Time-of-Flight (TOF) cameras, new opportunities using these devices have opened up for a variety of applications. In this White Paper, we compare Infrared (IR) illumination for TOF systems using Vertical Surface Emitting LASERs (VCSELs) and Light-Emitting Diodes (LEDs)–and show that LEDs can hit the “sweet spot” for TOF.
