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 tasksand 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.

The automotive industry is one of the most regulated industries in the world. In order to keep up with the increasingly strict safety standards, manufacturers are in need of equipment with higher accuracy than ever before. Using Radiant’s “Points of Interest” tool in our ProMetric® Software, combined with a high-resolution ProMetric I-series Imaging Colorimeter, automotive manufacturers and suppliers can easily measure an entire headlamp beam distribution in a matter of seconds.

data transfer with ethernet connection

Radiant imaging colorimeters are sophisticated precision tools that allow users to collect mountains of data, but that much data can take time to transfer. USB 2.0 ports are only able to transfer a maximum of 480 mb per second, whereas an Ethernet connection can transfer up to 1 gb per second.  That’s a big difference! So why not increase your transfer speed by using your ethernet connection?

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 factors). The crux of the matter is that displays are more critical to device function and control than ever before. Think about it—how many analog components have been replaced by displays in this year’s vehicles? Beyond GPS panels, displays now function as consoles for all vehicle controls, including navigation, entertainment, heating and air conditioning, and even dashboard indicators and gauges. This trend continues in appliances, aerospace, commercial buildings, manufacturing spaces, and beyond. Displays are everywhere, and they are becoming central to the way we accomplish everyday tasks...

Recalibrating a Camera

When you drive a new car off the lot, you expect that it will require periodic maintenance throughout its lifetime to ensure it performs at its very best. Much like a car or other sophisticated machinery, we recommend regular recalibrations of your Radiant colorimeters and photometers. Recalibration finetunes the camera to ensure continued operation within our specifications and tolerances. Neglecting regular recalibration for long periods of time can result in debris and dust particles in the camera, dead pixels, out of spec performance, and moisture retention.

Judging Display Quality: Humans versus Imaging Colorimeters

Replacing human inspectors with imaging colorimeters is one way manufacturers can ensure improved, consistent quality in the displays leaving the factory. Imaging colorimeters replicate human visual perception, meaning they “see” light and color the way a human does. In other words, an imaging colorimeter is a digital human eye. It combines the accuracy of human vision with the high repeatability of an automated system. This combination makes an imaging colorimeter superior in inspection applications than its human counterpart. Here’s why...
