Three-dimensional sensing technology is the foundation of multiple new applications, such as:
Facial and gesture recognition
Eye tracking and iris detection
Lidar for autonomous vehicles, drones, robotics
Simultaneous localization and mapping (SLAM)
Other near-infrared 3D sensing applications
Measurement techniques for NIR LEDs and lasers ensure the performance of Time-of-Flight (ToF) light-based proximity sensing and 3D sensing using dot patterns produced by diffractive optical elements (DOE). To ensure performance and accuracy of devices and systems that use NIR sensing, an effective test and measurement solution is needed.
The Radiant Vision Systems Near-Infrared (NIR) Intensity Lens system is an integrated camera/lens solution that measures the angular distribution and radiant intensity of 850 or 940 nm* near-infrared (NIR or near-IR) emitters. The NIR Intensity Lens system utilizes Fourier optics to capture a full cone of data in a single measurement to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control.
Manufacturers of 3D sensing technology can apply the NIR Intensity Lens solution for angular measurement of NIR LEDs, lasers, and structured light patterns produced by Diffractive Optical Elements (DOE). The lens mounts directly to a Radiant Vision Systems ProMetric® Y16K Imaging Radiometer, and features ProMetric or TrueTest™ Software for intuitive system setup and customizable automated measurement sequences. Additional tests specific to NIR emission measurement are available.
