Machine vision has been a boon to manufacturers, offering quality inspection at production line speeds. However, some visual inspection tasks are beyond the capability of traditional machine vision, such as cosmetic surface inspection. Only human inspectors have been able to provide the visual acuity to spot subtle defects and make sure that products look perfect to the end consumer. Now, Radiant's Advanced Vision approach uses photometry-based imaging to match the precision of human inspectors, but with the benefits of automation for speed, consistency, and data capture.

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

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.
