As display screens proliferate in our daily lives—from mobile phones and tablets, to automobile GPS and smart home devices—the way we interact with them is increasingly dynamic; we look at them from many angles and on the go. To ensure that flat panel displays are clear and usable, manufacturers need to test performance from multiple viewpoints. Radiant's FPD Conoscope Lens captures a full cone of view angle data in a single measurement to ±70 degrees.

Photometry-based imaging systems—like Radiant’s INSPECT.assembly™ solution—now offer superior inspection capabilities for high-precision assembly verification: visual detection capabilities that match or exceed the acuity of human inspectors, with the speed, repeatability, and quantifiable data of automated machine vision systems.

Augmented and virtual reality headsets present images to the user on near-eye-displays (NEDs): display screens that are in close proximity to the eye. This proximity enhances the immersive experience for the user, but can also magnify any slight imperfections on the screen. Ensuring the quality of NEDs within AR/VR headsets requires a test solution that can "see" everything the wearer sees. Radiant has introduced a specially designed AR/VR lens that replicates the perspective and placement of the human eye to provide the most effective qualty testing for AR/VR devices...

Today kicks off the 3rd annual Automotive Visual & Display Technologies (AVDT) event in Ann Arbor, Michigan (March 26-28), where leaders in automotive engineering, design, and manufacturing will discuss the next generation of car HMIs (human machine interfaces) and display integration. My colleague Matt Scholz presents a conference session this afternoon titled “New Measurement Methods to Solve Emerging Display Test Challenges.” (If you happen to be reading this blog from the show, check out Matt’s talk at 3:20 PM!) As I explore the AVDT agenda—with topics covering head-up displays to human-centric design and autonomous vehicles—it’s clear that we’re on the verge of a new automotive era...

Sensing systems like LiDar, cameras, ultrasound, and radar are enabling the technology of self-driving (autonomous) vehicles. In this post, we take a look at LiDar (that uses laser pulses). Radiant's NIR camera lens can measure LiDar and other near-infrared emissions.

What makes CCD-based imagers ideal for measuring luminance and color as humans perceive them? What's a "tristimulus curve?" Learn a little bit of light and color physics and understand how the high-resolution capabilities of CCDs, in combination with CIE-matching filter systems, can accurately represent how the human eye sees color.

OLEDs are the pivotal technology that are (literally) changing the shape of displays. Since each OLED is individually lit, there is no backlight required, enabling a thin display that can even be rolled or folded, like a piece of paper. This flexibility has diversified the application of displays, making OLED the next target tech for major manufacturers.

Visit us at booth #3815 at IPC APEX EXPO this week for a live demonstration of INSPECT.assembly™, a turnkey inline assembly verification station that automates the process of complex component inspection. Using photometry-based technology, INSPECT.assembly detects subtle defects in complex electromechanical assemblies that traditional machine vision can miss, such as the presence or absence of low-contrast components.

Virtual reality systems can provide remarkably realistic images and experiences—like putting you right on the slopes of the Olympic games in South Korea. But VR, augmented reality (AR), and mixed reality (MR) devices rely on the quality of near-eye displays (NEDs) to deliver a seamless immersive experience. With images in close proximity to the human eye, even minor display defects are magnified, making display quality testing a critical step for product quality control. Learn about Radiant's new AR/VR lens for display testing that simulates the perception and perspective of the human eye.

While machine vision systems are sufficient for many types of inspections tasks—and offer benefits of quantifiable, actionable data—the downside is that they just aren’t suited to high-precision, low-contrast, and challenging assembly verification. To fill the gap, human inspectors are still widely used when their discernment, visual acuity, and ability to detect and judge unexpected defects is required to ensure product quality. A new inspection solution option is now available for these kinds of challenging inspection tasks, that offers the speed and repeatability of machine vision with the visual discernment of the human eye.
