The use of augmented (AR), virtual (VR) and mixed reality (MR) devices is burgeoning in enterprise environments—from the R&D lab to the factory floor and out in the field, with a broad range of applications such as training, design and product development, maintenance/repairs, and quality assurance.
Use of augmented reality (AR) technology is expected to boom in the coming decades. Leading the way in AR adoption is the industrial sector, which includes manufacturing, engineering, electronics, automotive, aerospace, and other verticals with heavy physical components.
Uses and potential applications of augmented (AR), virtual (VR), and mixed (MR) reality devices are growing rapidly in industries as diverse as gaming, military, education, transportation, manufacturing, and medicine.
Liquid crystal on silicon (LCoS or LCOS) is a microdisplay technology using a liquid crystal layer on top of a silicon backplane. The technology, a type of “spatial light modulator” (SLM), offers high resolution, contrast, and black levels compared to competing technologies such as liquid crystal display (LCD) and digital light processing (DLP).
As display resolutions increase, imaging systems are challenged to continue to provide accurate pixel-level measurements while applying increasingly limited relative imaging resolution during single-image analysis (necessary for production efficiency). A fractional pixel registration and measurement method improves the accuracy of pixel-level values measured by standard-resolution systems, ensuring effective qualification and demura of high-resolution OLED, miniLED, and microLED displays.
As display resolution and pixel density increase, measuring the characteristics (luminance, chromaticity) of individual display pixels becomes more difficult for current imaging technology. Single-image analysis is important for optimizing efficiency for viable production processes. Imaging systems must continue to accurately measure the increasing number of pixels in a display at once, applying increasingly limited relative imaging resolution.
The concept of metamaterials has been around for a while, but the last two years has seen a surge in scientific and fabrication breakthroughs that could soon usher in a new age of optical techniques and capabilities based on metalenses. The term “metamaterials” was coined from the Greek word meta, which means “beyond”—metamaterials go beyond normal materials in the sense that the natural properties of the materials have been altered.
In the real world, when we see an object, it’s actually our eyes receiving light reflecting off that object—a wavefront of light. The wavefront incorporates complex information that our eyes can interpret about brightness, color, and distance (phase) properties of the light waves, which enable us to perceive the object in three dimensions (3D).
Imaging systems are highly efficient visual inspection tools, enabling contextual analysis of the complete area of a display, including deviations in luminance, color, and other characteristics. The process of converting light into digital input to create an image, however, is not precisely one-to-one. Imaging sensor types accomplish this conversion process in different ways, each with distinct benefits and limitations.
Augmented, virtual, and mixed reality (AR/VR/MR) devices and other head-mounted displays (HMDs) are unique in the display industry as they are intended to be viewed at very close range. Unlike televisions seen from across a room, or smartphones held at arm’s length, these appropriately named Near-Eye Displays or Near-to-Eye Displays (NEDs) are typically positioned a mere 1.2 - 3 inches from the user’s eye.
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.
As display resolution and pixel density increase, measuring the characteristics (luminance, chromaticity) of individual display pixels becomes more difficult for current imaging technology. For instance, the imaging system that I use to measure my display may have an image sensor boasting 29 megapixels (29MP; or around 29,000,000 pixels). Each of these image sensor pixels (tiny light-sensing or photo-sensitive elements) enables me to measure the light emitted from each pixel in a display.
FPDisplay sits with Radiant Technical Director, Li Sun, during the 8th China Information Technology Expo (CITE 2020) in Shenzhen to understand how Radiant continues to innovate in step with—and ahead of—the display market.

Disruptive technology like augmented and virtual reality devices lay the foundation for future innovation, and also put demands on the vision and imaging equipment used to ensure the quality of a digital experiences that are blended with reality.
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.
Projecting speed, navigation, and alerts onto the car windshield—directly in the operator’s field of view—offers safety and design advantages that have made head-up displays (HUDs) the vehicle segment with the highest expected growth rate in the automotive market (Source: Mordor Intelligence, Automotive Head-up Display Market - Analysis of Growth, Trends, and Forecast (2018 - 2023)). Already introduced in several new vehicles, HUD technology is evolving rapidly.
Despite what their name might suggest, microdisplays are not necessarily microscopic—but they are pretty tiny. For example, at 2018 SID Display Week, BOE showed off a microdisplay screen that’s smaller than a penny:
