Chris Williams from Radiant Vision Systems a Konica Minolta company, chats to Tom Selway at AutoSens in Brussels 2018. Recorded at AutoSens Brussels 2018, the world's leading vehicle perception conference and exhibition, held at AutoWorld Museum, Brussels and coming to the USA in May 2019 at the Michigan Science Center, Detroit.
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 Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies.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.
Early Model-T Ford vehicles didn’t even have a speedometer (their top speed was just 35 mph), but soon after, dashboards began to include multiple gages, indicators, and vehicle controls. (Fun fact: the word ‘dashboard’ originates from horse-drawn wagons and carriages, where a board at the front protected passengers from mud that was ‘dashed’ up by the horses’ hooves.)
Automobiles are getting smarter and smarter—various integrated camera and sensing systems can now help you back up safely, park, avoid a collision, stay in your lane, alert you to a vehicle in your blind spot, and supplement your vision at night, among other features. The Advanced Driver-Assistance Systems (ADAS) that have these capabilities typically use embedded-vision, RADAR, and/or LiDAR-based technology to continuously monitor the environment outside the vehicle.
Charge-coupled device (CCD) sensors are used in many of today’s advanced digital cameras and imaging systems. CCDs were first developed in 1969 by physicists Willard Boyle and George Smith. They based CCD technology on Albert Einstein’s theory of the photoelectric effect, through which light is converted into electrons. A CCD sensor captures those electron signals in the form of image points, or pixels, enabling them to be read digitally.
In this article, we discuss unique measurement considerations for ensuring the quality of LED sources, and equipment for measuring LED displays, individual sources, and luminaires.
In this article published by Global LEDs/OLEDs, Radiant surveys a number of measurement methods that generate either near-field or far-field models of the LED or luminaire and evaluate their strengths and weaknesses to guide us in selecting the right measurement method for the application.
LEDs remain a pivotal light-emitting element in a range of lighting products and displays. For manufacturers of these devices, it is important to evaluate the performance of LEDs and LED-based systems in objective and meaningful ways.
In this article, we describe a method for the measurement of large light sources in a limited space that efficiently overcomes the physical limitations of traditional far-field measurement techniques. The measurement is performed from within the near-field of the light source, enabling a compact measurement set-up, and generates a detailed near-field color and luminance distribution model that can be directly converted to ray sets for optical design and that can be extrapolated to far-field
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.
Take a look at the basic operating principles and performance tradeoffs of imaging colorimeters, a class of instruments that enable spatially resolved measurements of color and luminance that are directly applicable to displays and solid-state sources.
Imaging colorimeters excel at inspecting a range of qualities of a light source in a single measurment, thanks to significant spatial resolution that is able to capture and analyze the unifomity of light and color across an entire light source at once.
Editor in Chief of SID Information Display magazine, Jenny Donelan, interviews Radiant Vision Systems Chief Solutions Officer, Doug Kreysar, on the history and growth of Radiant Vision Systems. This article includes a Q&A with Radiant CSO Doug Kreysar and discusses the company's target markets, growth into the machine vision inspection sector, and new product releases in AR/VR display measurement for augmented and virtual reality devices.
The invention of the electric light bulb changed the world. It enables human activity at all times of day or night, and in all ambient light conditions. The first commercially available bulbs were released in 1880, manufactured by Thomas Edison’s company, the Edison Electric Light Company. The resulting demand for electric lighting propelled the building of vast electrical distribution infrastructure to bring power to homes and businesses in the following decades.
Do your childhood holiday memories include untangling long strings of tiny lights and going through a laborious process of elimination to identify that one burned-out bulb that was causing the whole string to malfunction? Well, lighting technology advances have solved that problem with long-lasting (10 year+) LED bulbs and strings that stay lit even if one bulb goes out.
In this article, learn how photometric and colorimetric technology matches the visual sensitivity of human vision. We discuss the advantages and applications of CCD imaging for light and color measurement, as well as component and surface inspection, that most accurately reflects the human visual experience.
Every light source in a vehicle must be measured to ensure its effectiveness for its application. Headlamps must adhere to roadway illumination standards for proper beam shapes, distributions, and intensities for illuminating areas outside the vehicle. Inside the vehicle, LED-backlit components rely on consistent brightness and color—as well as cross-component harmonization—to convey a vehicle’s quality in both function and aesthetic.
