Upcoming Webinar: Principles of Light and Color Measurement

The properties of light that stimulate the eye and build our visual perception—when thoughtfully designed into lighted devices—can create unrivalled visual experiences. Thanks to well-established scientific methods, we can quantify the human eye’s response to light in a mathematical context for use in optical metrology. Light measurement systems like imaging photometers and colorimeters use CIE-matched optical filters and scientific CCDs to apply these methods, capturing meaningful data that guide human-centric design and evaluation of many of today’s devices. Using photometric technology, manufacturers can leverage the standard principles of light and color measurement in design and production to best assess the visual quality of displays, backlit components, and light sources—as they are actually seen and experienced by human users. This provides manufacturers with the means to achieve absolute product quality.Join a webinar hosted by Shannon Roberts, Product Manager at Radiant Vision Systems, as she presents the basic principles of light and color measurement. Shannon will discuss the foundation of photometry and introduce photometric technologies that leverage these principles to accurately quantify the human visual response to ensure quality in light and display products.

Defining a Sparkle Measurement Standard for Quality Control of Anti-Glare Displays

Displays are increasingly integrated into environments where variable light conditions are common, like vehicle consoles and dashboards. Anti-glare (AG) films are applied to displays to minimize reflections from ambient light and ensure that important information is viewable. The variable surface structure of the AG film allows ambient light to be diffused evenly, but can also compete with the pixel geometry of the display as light is emitted through the film. As display pixels near the size of the facets in the AG film structure, a visual effect called sparkle results, causing low display clarity that can appear grainy to a human observer. Measuring perceived sparkle ensures that the user experience drives the manufacture of AG displays. Such a measurement can be used not only in quality control during display production, but also in supplier qualification by OEMs who source third-party displays for integration.In this 50-minute webinar, International Senior Business Advisor for Radiant Automotive applications Matt Scholz presents a method for repeatable sparkle measurement across users, devices, and systems, with quantifiable results that correlate to human visual perception of display quality. Topics include:The effect of sparkle on display qualityStandard system specifications and setup for repeatable measurementSetting a sparkle tolerance based on human visual perceptionCustomer case study at automotive OEMAn audience Q&A with our presenter follows the presentation.

Replicating Human Vision for Accurate Testing of AR/VR Displays

Near-eye displays – like those used in augmented (AR), virtual (VR), and mixed (MR) reality devices – project visual objects and information in close proximity to the human eye, sometimes encompassing the user’s entire angular field of view. This proximity not only magnifies display projections, but also enhances defects like non-uniformity, line and pixel defects, poor image clarity, and image positioning issues. To accurately test the quality of displays that are viewed so near to the eye, the measurement solution should take into account the position, limitations, and characteristics of the human eye, especially within the unique viewing environment of an AR/VR headset.In this 30-minute webinar, host Eric Eisenberg, Applications Engineering Manager at Radiant, presents solutions for near-eye AR/VR display testing that replicate human vision for the most accurate evaluation of the user experience.

Achieving Automated In-Line Inspection Beyond the Precision of Human Vision

Today’s electronics manufacturing processes are largely automated. However, final inspection for connected assemblies has lacked an effective automated solution that achieves both highly-repeatable and highly-accurate defect detection. At the final stages of production where internal components are verified before device enclosure, human inspectors remain the primary inspection method. This is due to superior human visual acuity and judgment over typical machine vision systems for complex visual analysis. However, human inspection lacks the desired autonomy and consistency of machines.In this 30-minute webinar, host Davis Bowling, Regional Sales Manager for Radiant North America, presents a new turnkey inspection solution that leverages advanced vision technology to achieve unrivaled accuracy and repeatability, bridging the gap between human inspectors and machine vision systems.

OLED Pixel Measurement & Correction

Organic light-emitting diodes (OLEDs) enable the latest advances in display technology, but because each OLED pixel acts as its own emitter, brightness and color from pixel to pixel is characteristically inconsistent. The level of non-uniformity in OLED displays varies not only from product to product, but even among devices within the same product lot, challenging manufacturers of OLED devices to meet the market’s high expectations for quality at a pace that matches demand.Automated visual inspection systems like imaging colorimeters offer the optical resolution necessary to measure OLED displays on the pixel and sub-pixel level. With these measurements, pixel-level correction can be performed on low-quality displays to improve the yield of quality devices in-line. This process, referred to as OLED Demura, adjusts the luminance and the chromaticity of each OLED pixel to produce displays with an entirely uniform appearance.In this webinar, Radiant Optical Software Engineer Alex Podschwit presents solutions for OLED pixel-level measurement and correction and describes a Demura method using high-resolution Radiant colorimeters and software.

Solutions for IES/LDT File Creation

Luminous intensity data is critical for lighting design. Captured in photometric data files, luminous intensity data enables lighting designers to observe the total output and angular spread of a light source. IES and EULUMDAT (LDT) are the two standard file formats used for electronic transfer of photometric data. To create IES and LDT files, designers have their choice of systems. Traditionally, goniophotometers have been used to generate very accurate photometric data, but these systems require very large lab spaces and expensive equipment. An alternative solution uses a near-field measurement system, which can generate equally accurate data with minimal lab space, increased speed, and lower cost. In this webinar, Radiant Applications Engineer Austin Piehl presents solutions for creating IES and LDT files and demonstrates the process of analyzing light measurement data and exporting these files using Radiant’s PM-NFMS™ Software. Topics include:Solutions for IES and LDT file creation, from conventional goniophotometry to near-field measurement systemsThe process of collecting light measurement dataTypes of data acquired: comparing near- and far-field dataApplications of Radiant’s ProMetric® Near-Field Measurement System (PM-NFMS)Considerations for the LM-79 methodAn audience Q&A follows a presentation and demonstration of Radiant’s PM-NFMS Software for IES and LDT file generation.

Improving Automotive Inspection with Light & Color Measurement Systems

Vehicles are more illuminated than ever before. Adaptive headlamps guide our way in changing light and weather conditions, head-up displays (HUDs) provide real-time information about our surroundings, and infotainment displays enhance the driver and passenger experience. A vehicle's safety and perceived quality are increasingly contingent on the quality of light in these various displays, which must be measured to control the precise and meaningful variations in brightness and color. While standard machine vision systems can evaluate images for limited pixel-level contrast variations to detect defects, variations of light and color as perceived by humans are much too delicate for standard 2D imaging.In this webinar, Radiant Vision Systems introduces light and color measurement solutions designed scientifically to evaluate light using the same perception tolerances as the human eye. Webinar host and Radiant's Automotive Business Leader, Matt Scholz, presents methods for using photometric and colorimetric cameras for brightness and color evaluation.
