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.
This paper describes precise geometric, optical, and software parameters of a sparkle measurement method, which has been proven to match human visual perception of display quality with repeatable results. Using this method, OEMs and manufacturers of displays can define precise, measurable tolerances for sparkle and establish standard quality control processes for anti-glare displays.
The Microscope Lens mounts to any ProMetric® Imaging Coloriemter or Photometer to enable high-resolution imaging of extremely small components and features, such as individual LEDs and display pixels. Provides 5X and 10X magnification, capturing a greater number of CCD pixels per display pixel or component feature for fine-detail measurement.

These days we’re even more reliant on our screens than Snow White’s queen was on her magic mirror. Considering their importance, the need for quality and clarity in displays—from televisions and smart phones to automobile dashboards to VR headsets—is no fairy tale. Mura is a Japanese word that means unevenness, irregularity, or blemish.
The Near-Infrared (NIR) Intensity Lens system is an integrated camera/lens solution that measures the angular distribution and radiant intensity of 850 or 940 nm near-infrared (NIR or near-IR) emitters. The NIR Intensity Lens system utilizes Fourier optics to capture a full cone of data in a single measurement to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control.
The NIR Intensity Lens system is an integrated camera/lens solution that measures the angular distribution and radiant intensity of near-infrared (NIR or near-IR) emitters, such as LEDs and lasers. The NIR Intensity Lens system utilizes Fourier optics to capture a full cone of data in a single measurement to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control.
Measurement techniques for near-infrared (NIR) LEDs and lasers ensure the performance of Time-of-Flight (ToF) light-based proximity sensing and 3D mapping and identification using dot patterns produced by diffractive optical elements (DOE).
You’ve probably seen a moiré pattern before, even if you didn’t know the name for it. Moiré (pronounced “mwah-rey”) is the French word for a type of rippled textile effect. In photography, it describes an interference pattern—a form of aliasing—that can appear on images. For example, moiré can be seen on standard photographic or video images that contain a pattern or repetitive detail that exceeds the resolution of the imaging device.
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.
Light measurement systems like imaging photometers and colorimeters use CIE-matched optical filters and scientific-grade imaging sensors to apply these methods, capturing meaningful data that guide human-centric design and evaluation of many of today's devices. Watch this webinar to learn the foundations of photometry and colorimetry, and photometric technologies that leverage these principles to accurately quantify the human visual response to ensure quality in light and display products.
Radiant Vision Systems provides leading display test solutions for labs and production lines, with thousands of cameras testing millions of devices worldwide.
Engineered in response to OEM and supplier testing requirements, Radiant Vision Systems provides a comprehensive hardware/software solution to enable fully automated testing of head-up displays (HUD) in automotive and other integrations.
In movies, we've all seen the dramatic air combat sequence where a pilot uses guide lines to zero in on a target before firing a weapon. Those on-screen guides are a head-up display (HUD), so called because the pilot doesn't have to look down at an instrumentation panel.
When out at sea, a ship’s captain needs instant access to clear and accurate information to navigate and maintain vessel operations and safety. In the early days of cross-oceanic sailing, instruments like a compass, telescope, sextant, and hourglass were among the few tools that mariners had to help them on the journey. Today, a panoply of electronic instruments, sensing systems, and display screens offer seafarers extensive real-time information and advanced communications capabilities.
Displays are increasingly integrated into environments where their positions are fixed relative to the viewer and variable lighting conditions are common, such as vehicle consoles and dashboards. Because of their role in operation and safety, these in-vehicle displays must be viewable in all types of ambient lighting conditions.
Projecting speed, navigation, and situational 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.1
Air travel can be an uncomfortable experience, and these days passenger anxiety is running high with pandemic concerns. Interior cabin lighting can be an important factor in helping to create a more relaxing, comfortable atmosphere aboard flights. Light—including qualities such as brightness, saturation, and hue—has been shown in multiple studies to affect human moods, energy levels, appetite, and circadian rhythms.
Head-up displays (HUDs) were a hot topic in the automotive industry in 2018, and that trend is only going to continue in the new year as more and more automakers incorporate HUDs to enhance safety and functionality of new car models.
Human visual perception is the ultimate standard of quality for any lighting or display product that’s intended to be viewed by humans. No machine vision or other sensing system has been able to fully replicate the level of discernment and accuracy of the human eye, but we can get very close using CCD-based imaging technology.
Display quality has never been more valued than it is today—and not just because we want the ultimate HDTV experience or the prestige that comes with owning the latest OLED smartphone (although these are definitely fa
