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. Learn mor about NIR facial recognition quality and safety considerations, and how Radiant's new NIR measurement solution can help you ensure NIR light sources are perfoming to spec.

First there were LED displays, now microLEDs and miniLEDs have come on the scene, with examples of both types of displays seen in proliferation at the recent 2019 Consumer Electronics Show (CES). Understand what differentiates these small LED types and the various applications where they are—or soon will be—in use, from gaming displays and televisions, to augmented reality and exterior signage.

HUD Quality Challenges
Head-up displays (HUDs) pose unique measurement challenges for manufacturers, combining photometric (light) and dimensional (spatial) data to ensure the accuracy of information conveyed to a vehicle operator within a rapidly changing, real-world environment. Radiant introduces a new module of our TrueTest™ software that provides a complete HUD measurement solution.

From computer keyboards to movie theaters, from car dashboards to airplane fasten-seatbelt signs, backlit symbols are all around us. A backlit sign is illuminated by a light source that is placed behind a stenciled surface that allows light to shine through, creating illuminated text and symbols. LIght and color measurement systems from Radiant help manufacturers ensure that backlit devices and signs are clear and visible—especially in cars and aricraft, where they convey key safety information.

Virtual reality has been referred to as the “ultimate empathy machine” since it allows users to experience any situation from any point of view. Studies have shown that AR/VR can shift a user’s attitudes and feelings, increasing both self-confidence and compassion for others. The immersive nature of virtual reality is what makes for such a powerful experience, but only if the AR/VR device works as intended. Effective development and QA testing helps ensure display and performance quality.

Head-up display (HUD) systems in automobiles offer safety and design advantages, by projecting speed, navigation, and situational alerts onto the car's windshield directly in the driver's field of view. Two-dimensional, fixed-distnace displays are starting to come on the market; but the next generation of 3D and augmented reality displays are already set to overtake them. How does the process of HUD measurement change with the incorporation of 3D and AR-HUD systems, which project new types of virtual images, across larger fields of view, and at a range of depths?

Albert Einstein's discovery of the photoelectric effect not only helped to resolve the quandry of whether light is a particle or a wave (it's both). But also led directly to the development of CCD sensors, the fundamental technology behind today's digital photography and imaging. Learn more about the science of CCDs and how they work to create detailed and precise images that a broad range of applications, from light & color measurement to medical imagaing.
