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.
Radiant Vision Systems provides visual test and measurement systems that characterize and inspect light and color for quality in display design and automated production. Their inspecting processes and tools are used in LCDs, LEDs, microLEDs, and OLED for flat panel displays, head-up displays, AR/VR, and near to eye displays (NEDs).
KGNOW interviews Optical Software Engineer James Wheeler and Director of Marketing Cathy McBeth of Radiant Vision Systems from the floor of the 2018 Display Week by SID (Society for Information Display). James explains their capabilities including software and hardware packages from head mounted displays for virtual reality to head-up displays for automotive.
Today's automated solutions enable a range of simple FDP inspection tests that far exceed the capabilities of human inspectors in terms of reliability and objectivity, and yield much greater ROI in application.In this 30-minute webinar, Radiant's Hubert Kostal describes three key benefits of imaging colorimetry for automated inspection of FPDs and offers:
Human perception will always be the ultimate gauge of quality when it comes to flat panel display appearance. After all, the end user of a smartphone, tablet, PC, and TV is a human – one who will spend a lot of time looking at, and enjoy, or not, interacting with it. Colors that are off, non-uniform appearance, or other defects will result in a poor experience.
There’s a lot of data used to characterize electronic displays: resolution, pixels per inch, refresh rate, luminance (nits), pixel pitch, dynamic range, contrast ratio, etc. All this information is meant to help convey the quality of a display. But ultimately, it is the visual experience of human users that will define a display’s performance—and largely determines its success in the marketplace.
Since they first emerged on the market in the 1980s, laptop computers have become essential to our list of equipment for both work and personal use. As coronavirus stay-at-home orders increased, many consumers rushed to upgrade their home computing systems and many companies had to provide their employees with new hardware and systems to support remote work.
Optics is the study of the origin and propagation of light, how it changes, what effects it produces as it interacts with matter, its various phenomena, and the instruments used to study it. Optics includes the study of sight—how we see. All light is electromagnetic radiation, some visible to the human eye, and some invisible (for example, infrared light).
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.)
CCD (Charge Coupled Device) and CMOS (complementary metal-oxide semiconductor) sensors work by converting light into electrical current (electrons), allowing images to be recorded digitally, in pixels.
Today’s electronics customers expect flawless device quality right out of the box, and that holds just as true for keyboards as it does for smartphones or televisions. Device quality is paramount—just ask this Reddit user, who posted a complaint about tiny cosmetic defects on a keyboard.
Display technologies continue to evolve rapidly. As the trend continues toward larger, higher-resolution screens, and emerging technologies pose new challenges on the production line, manufacturers need inspection systems that will ensure a flawless product without impacting production speeds.
This article introduces methods for meeting the requirements of the new SAE J1757-2 standard for head-up display measurement and outlines the advantages of automated measurement systems.
Displays viewed near to the eye create immersive virtual experiences, such as those integrated into AR/VR devices. However, as display images are magnified to fill a user’s field of view (FOV), display defects are also magnified. Radiant provides an application-specific display test solution to meet the unique measurement parameters of NEDs viewed in close proximity through AR/VR headsets and goggles.
Coronavirus concerns have forced many organizations to rethink how they operate, find new ways to connect employees, and shift to remote work. This has driven a massive shift to online platforms that offer video conferencing, group chat, and virtual collaboration. With this virtualization of large segments of global business activity, augmented- (AR) and virtual-reality (VR) technologies have been thrust into the spotlight, with an increasing number of useful applications.
So much innovation is happening in the fields of augmented reality (AR) and virtual reality (VR) these days, with a wide range of emerging practical applications. AR/VR is revolutionizing everything from medicine to manufacturing to museums. Recent examples include “workers assembling wind turbines at a
Augmented reality (AR) may be hot in the marketplace right now, but it’s nothing new in military aircraft. “It’s been around for nearly 60 years,” says Chris Colston, director of strategic growth at BAE Systems, which built the first head-up display (HUD) for the Blackburn “Buccaneer” aircraft that launched in the late 1950s. “We’ve supplied AR solutions long before that meant anything to the mass market.”1
As employers and workers around the globe adjust to life during a pandemic, many companies have had to rethink how they structure the workplace to incorporate remote, virtual, and hybrid models. Many are reevaluating the pros and cons of having a remote/geographically distributed workforce, not only due to COVID-19, but as a possible longer-term option.
Head-up displays (HUDs) project images onto ambient real-world scenes at infinite focal distances. This unique viewing context poses a challenge for ensuring image visibility and position, especially when it comes to meeting all requirements of established quality standards. Photometric measurement of light and color is equally important as dimensional measurements for image size, distance, location, and integrity in performing comprehensive HUD evaluation to SAE standards for optical quality.
Instrument clusters, symbols, and indicators on the dashboard of an automobile are crucial for the safety and performance of the vehicle. Typical indicators in modern cars include the speedometer and temperature gauges; symbols to indicate if a door is open, a passenger is not strapped in, or the parking break is engaged; a warning light when the gas tank or oil pressure gets low; or the “check engine” light indicating a malfunction.
