Near-infrared light enables autonomous vehicles to perceive the surrounding environment; it can illuminate the environment for infrared thermal imaging cameras to detect objects and their locations. It can track the user's eye movements in AR and VR headsets; it can use reflected light to unlock smart devices to interpret three-dimensional facial features.

Measuring light sources such as near-infrared LEDs and vertical cavity surface emitting lasers (VCSELs) can ensure the performance of these systems and meet eye safety requirements. However, modeling the three-dimensional output of a light source for accurate evaluation has historically relied on large, complex, and expensive angle measurement systems, or on limited data captured by projecting the light source on a two-dimensional wall or screen.

Visitors to the Western Optoelectronics Market will have the opportunity to watch these products and other demonstrations of Radiant's automatic visual inspection system for light sources and displays. During the virtual event, Radiant’s global staff will be online and accessed through Radiant’s exhibition page in the market for real-time one-to-one chat, file sharing and video conferencing to answer questions about metrology using scientific imaging, dedicated optics and software Problem package.
