Combining an imaging radiometer and Fourier optics limits the complexity of NIR measurement by capturing all angular emissions within a single two-dimensional image, in a matter of seconds.
REDMOND, Wash. (PRWEB) November 18, 2019
Radiant Vision Systems, the leading provider of automated visual test and inspection solutions for light sources and displays, announced today that its NIR (Near-Infrared) Intensity Lens has been recognized among the best by the 2019 Laser Focus World Innovators Awards. An esteemed panel of judges from the optics and photonics community recognized Radiant Vision Systems as a Gold honoree.
“On behalf of the Laser Focus World Innovators Awards, I would like to congratulate Radiant Vision Systems on their Gold-level honoree status,” said Laser Focus World Editor in Chief John Lewis. “This competitive program allows Laser Focus World to celebrate and recognize the most innovative products impacting the photonics community this year.”
Radiant was honored with a Gold-level award for its new NIR Intensity Lens solution, released January 7, 2019. The NIR Intensity Lens is designed to measure NIR-emitting LED and laser sources—for example, vertical-cavity surface-emitting lasers, or VCSELs—used in non-visible 3D sensing applications such as facial and gesture recognition. Radiant’s NIR Intensity Lens is mounted directly to a Radiant ProMetric® Y16 (16-megapixel) Imaging Radiometer and uses Fourier optics to enable single-image analysis of the full angular distribution of an NIR light source to +/- 70 degrees. The system is designed for precise measurement of 940-nanometer wavelength sources—used by the majority of 3D sensing devices in consumer electronics as well as other applications. Paired with a specialized software test suite for NIR source measurement (Radiant’s TT-NIRI™ software module), the lens solution can be used to measure emission uniformity, total flux, and radiant intensity of sources including fall-off and hot spots of flood sources (used for time of flight (ToF) applications) and accurate angular position of structured light dot patterns containing tens of thousands of emission points.
“Capturing NIR emissions in angular space—especially thousands of emission points required for dot-pattern facial recognition—is extremely challenging for traditional measurement equipment,” said Doug Kreysar, Executive Vice President and Chief Solutions Officer at Radiant Vision Systems. “Traditional systems like goniometers capture comprehensive angular data from light sources, but are large, costly, and may take hours to perform a complete analysis. Combining an imaging radiometer and Fourier optics limits the complexity of NIR measurement by capturing all angular emissions within a single two-dimensional image, in a matter of seconds. The Radiant NIR Intensity Lens system can accomplish angular NIR emission measurement using a compact camera/lens combination in place of large, multi-component goniometric systems, giving manufacturers a very space- and cost-effective laboratory measurement solution. The scale and speed of the NIR Intensity Lens system also makes it an optimal solution for production-level qualification, which would be impossible with a lab-based goniometer.”
