Radiant Demonstrates Optics for Light Source and Display Measurement

Radiant Vision Systems will give virtual product demonstrations of leading optical components for AR/VR display testing and near-IR light measurement at the first Photonics West Digital Forum, online March 6-11, 2021.

The application of light has diversified the way users interface with their devices, and how devices interface with their environments.

Near-infrared light enables autonomous vehicles to sense their surroundings; it can unobtrusively illuminate environments for infrared cameras to detect objects and their positions; it can track a user’s eye movements within AR and VR headsets; it can unlock smart devices using reflected light to interpret three-dimensional facial features.
Measuring light sources like near-IR LEDs and vertical-cavity surface-emitting lasers (VCSELs) ensures the performance of these systems and compliance with eye safety requirements. However, modeling the three-dimensional output of a light source for accurate evaluation has historically relied on large, complex, and expensive goniometric systems, or limited data captured by casting a light source on a two-dimensional wall or screen.

Visitors of the Photonics West Marketplace will have the opportunity to view these products and other demonstrations of Radiant’s automated visual inspection systems for light sources and displays. Members of Radiant’s global staff will be online and available from Radiant’s exhibit page in the Marketplace during the virtual event for live one-on-one chat, file sharing, and video conferencing to answer questions about metrology using scientific imaging, specialized optics, and software packages.
