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.
Augmented reality (AR) falls into the category of “spatial computing”—a merger of digital and physical space. Nowhere does this concept hold greater potential for life-changing applications than in medicine. Use of AR, along with virtual (VR) and mixed reality (MR), in the healthcare industry is projected to reach a global market size of US$ 7.05 billion by 2026, growing at an explosive 28.3% compound annual growth rate (CAGR),1 including hardware and software.
Robots are getting better at doing more and more tasks—from devices that vacuum our homes, to drones that deliver packages, to robotic arms that help build automobiles. But one thing machine systems haven’t been able to do well until recently is match the acuity of human vision. Precise visual assessment is particularly important for inspecting products like electromechanical devices.
Medical devices—ranging from those for consumer personal use to those designed for clinical settings—must adhere to stringent requirements in their design and manufacture. Performance, accuracy, and reliability are vital when patient health is on the line. The increasing digitization of medical practice and care management has led to a boom in integrated medical devices.
In this article, Radiant Vision Systems Chief Solutions Officer, Doug Kreysar, contributes his thoughts on AR/VR technology development, which brings together camera systems, near-IR eye tracking, gesture recognition, and other machine vision capabilities that improve the visual performance and extend the application of AR/VR headsets.
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.

Human perception is the ultimate standard for determining the visual quality of a display. For this reason, human inspectors have traditionally been used for quality control inspection of products like display devices. However, using human inspection can be problematic because of the statistical variation between observers.
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.
The development of medical imaging technologies has revolutionized healthcare, providing powerful diagnostic tools, supporting non-invasive assessment of injuries and internal issues, and enabling diseases to be detected far earlier than ever before.
This week, thousands of professionals in the optics, photonics, lighting, camera, lens, display, AR/VR, and related industries will be gathering in San Francisco for a series of events held by SPIE, the international society for optics and photonics. The first event (taking place currently) is the 3rd annual Augmented, Virtual, and Mixed Reality Conference, February 2-4 at Moscone Center West.
Scientific methods allow us to understand and quantify our perception of visible light and color. In this infographic, you will learn the language of light, understand color spaces and color matching functions, and other principles of light & color measurement. This tool is a useful reference for anyone with a passion for light metrology, or who works in applications dealing with light & color measurement.
Radiant Vision Systems provides leading display test solutions for labs and production lines, with thousands of cameras testing millions of devices worldwide.
“Help me, Obi-Wan Kenobi. You’re my only hope.” In 1977, these words first introduced Star Wars audiences to Princess Leia, perhaps the most famous hologram in history. Except, she wasn’t really a three-dimensional (3D) hologram—the projection was a product of movie special-effects magic, just an image on film, because 3D holographic technology didn’t exist at the time.
“Hard” inspection problems are ones that push the limitations of any visual inspection method—human or machine. As electronic and mechanical devices become more complex, assembly verification requires inspection of multiple features simultaneously and at high speed. Complex assemblies can contain many small parts or low-contrast elements that are difficult to assess at production speeds.
Back in the days when BlackBerry® phones were all the rage, I bought my first touchscreen laptop. It seemed like magic—just a few quick taps or swipe of the finger to open files, move things around on screen, and navigate the internet. Now most smartphones, eBook readers, and some MP3 players offer touch controls—and many laptops and automotive displays do also.
The electromagnetic spectrum of sunlight makes life possible—without it, earth would be a barren, icy ball of rock. From the weather systems that produce our temperate climates to the photosynthesis in plants that yields oxygen and food, light serves many essential functions. Lately, new uses for various wavelengths of light have been discovered or have risen to new prominence in the realms of healthcare, medicine, and well-being.
When we think of virtual reality (VR) and augmented reality (AR), the first thing that comes to mind is typically entertainment and games like VR sports or Pokémon GO. But the uses of this technology go far beyond recreation. In fact, AR and VR devices are poised to revolutionize medicine with new clinical applications and treatments.
The Radiant team introduces VIP™ Software—the first solution for backlit component inspection that combines the benefits of photometry for light & color measurement with machine vision for defect detection. Get an introductory presentation plus a software demonstration of this highly efficient, single-camera approach to measuring unique shapes and icons.
It was 125 years ago this month (November 8, 1895 to be precise) that German physicist Wilhelm Conrad Roentgen (1845-1923) discovered the existence of X-rays. He was in his lab conducting experiments with a cathode-ray tube (then called a “Crookes tube”) consisting of a glass bulb encapsulating positive and negative electrodes in a vacuum.
