In this booth interview with Laser Focus World, Shannon Roberts—Product Manager at Radiant Vision Systems—provides an introduction to the new Near-Infrared (NIR) Intensity Lens in a demo from the floor of Photonics West 2019, San Francisco, CA.
In today’s automobiles, versatile high-resolution touchpads have replaced analog gauges and knobs. Modern smart lighting adjusts to changing conditions. Radios have been replaced with multi-function, touch-sensitive infotainment displays. Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies. Head-up displays (HUDs) are becoming an automotive standard.
Biometric security measures—including fingerprint ID, iris and & retinal scanning, and voice recognition—are gaining popularity across the world due to increasing cybersecurity and privacy threats, accompanied by advancements in technology that make these identification methods possible.
Facial recognition technology is gaining popularity across the world due to increasing cybersecurity threats. While helping to prevent security issues, it also requires careful testing to ensure performance and accuracy. Radiant Vision Systems has developed a solution to measure near-IR light emissions with the introduction of the Near-Infrared Intensity Lens.
There are 62 million security cameras in the U.S. alone,1 and roughly 650 million facial recognition (FR) cameras worldwide,2 with millions more FR-capable devices carried around every day in people’s pockets.
Self-driving cars work, essentially, thanks to the presence of systems that allow a vehicle to “see” its surroundings. Replacing the ability of a human driver to spot objects, read traffic signals, and judge speed and distance is no easy task. Your car may already be equipped with back-up warning systems, parking cameras, or automatic braking for collision avoidance, but these are just support systems; you remain in control of the vehicle.
This paper discusses 3D sensing and how NIR light is used for facial recognition systems. It explains the importance of measuring radiant intensity of NIR emissions and the challenges of obtaining accurate measurement to ensure the quality of facial recognition systems in devices such as smartphones, laptops, and automobiles. It introduces Radiant's integrated NIR Intensity Lens solution and outlines the solution's advantages for evaluating NIR emitters for use in consumer products.
Near-infrared light—the range of electromagnetic wavelengths between roughly 700 nanometers (nm) and 1500 nm—is invisible to the human eye, making it ideal for an increasing number of 3D sensing applications such as facial recognition, iris scanning, gesture recognition, terrain mapping, automobile LiDAR, and night-vision security cameras.
Radiant Vision Systems discusses the importance of NIR measurement in facial recognition technology, measurement challenges, and technologies that enable measurement efficiency (including imaging, wide-field-of-view optics, and structured light pattern evaluation for characterizing NIR dot patterns used in facial sensing).
The Near-Infrared (NIR) Intensity Lens system is an integrated camera/lens solution that measures the angular distribution and radiant intensity of 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.

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.
