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.

The F-35 Generation III Helmet is currently the most advanced helmet-mounted display system (HDMS) in the world. It integrates with the F-35 Lightning II Joint Strike Fighter plane to provide an uprecedentel level of visual information, data, and responsiveness to support a pilot's situational awareness. Read more about the development and design considerations of this helmet and its head-up display (HUD), get a peek at the experience of being a modern "Top Gun" in the cockpit of this state-of-the-art aircraft, and learn about quality testing for HMDs, HUDs, and near-eye displays (NEDs).

Today's electronic devices like cell phones, laptops, and medical devices present increasingly complex assembly verification challenges. These "hard" inspection problems push the limitantions of any visual inspection method—human or machine. Assembly verification requires inspection of multiple features simultaneously and at high speed. If not caught, subtle defects—such as misrouted cables, missing screws, or misaligned connectors—can escape and end up in customer hands causing latent failures. The cost of these failures can be severe in terms of returns and warranty claims, customer dissatisfaction, and damage to brand reputation. Learn how photometry-based methods offer new capabilities to solve the hard inspection challenges.

The most important part of any camera is the lens, which directs incoming light to capture an image that mirrors reality. Today's highly sophisticated lenses are the result of a long history of optical and scientific experiments stretching all the way back to ancient civilizations. In this blog post, we look back at a bit of that history, examine how modern compound lenses work, and preview some innovative lens technologies of the future.
