Engineered in response to OEM and supplier testing requirements, Radiant Vision Systems provides a comprehensive solution to enable fully automated testing of head-up displays (HUD) in automotive and other integrations. In this video, Bret Stonebridge from Radiant demonstrates how a ProMetric® Imaging Photometer, electronically controlled lens, and TT-HUD™ Software enable rapid, automated visual inspection of HUD projections and virtual images. Using this solution, all qualities of optical HUD performance can be tested simultaneously. In this video, you will learn about:

The INSPECT.assembly solution is a fully-integrated inspection station that utilizes a Radiant Vision Systems imaging photometer, bright field lighting, and programmable software to detect subtle defects on complex assemblies and low-contrast parts and surfaces.
The Auto-POI (Automatic Points of Interest) functionality available in Radiant''s TrueTest™ software platform enables the automatic application of points of interest on backlit symbols using luminance values and chromaticity coordinates to define measurement thresholds. Once points of interest are defined, users can run pass/fail criteria against new values received, such as new parts entering a production line. Since Auto-POI is set based on light and color values, rather than static regions, symbol sets can accurately be measured regardless of location, position, size, shape, or color without reprogramming the POI parameters.
This video will cover:
- How to use the Auto-POI tool in TrueTest Software
- Measuring luminance and chromacitiy values of unique symbol sets
- Setting luminance and color thresholds to measure specific symbol sets
- Pass/fail analysis for luminance of symbols within symbol sets
Customers of today''s consumer electronics devices expect a flawless product out of the box. Scratched, dented, and otherwise imperfect products result in costly returns and may damage your brand''s reputation and future business. Quality control activities to prevent and detect surface defects rely largely on human inspectors. However, the faster the production rate, more complex the product, or more obscure the defect, the more difficult it is for humans to keep up with throughput demands while adhering to the need for absolute quality. Radiant''s high-resolution, low-noise imaging systems are engineered to measure and detect subtle variations in uniformity across components and surfaces. Our solutions combine the speed and consistency of automation with the discernment of human vision. Using advanced measurement capabilities, Radiant imagers are ideally suited for detecting anomalous features on surfaces and grading these defects based on their location, scope, and severity.
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 up to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control.
With the advent of new systems, display test equipment used to ensure HUD image quality is likewise facing new demands. How does the process of HUD measurement change with the incorporation of AR-HUD systems, which project new types of virtual images, across larger fields of view, and at a range of depths? Are you a manufacturer concerned with finding a measurement system that can address the evolution of HUD technology? Hosted by Matt Scholz, Automotive Business Leader at Radiant Vision Systems, this webinar presents an all-in-one HUD measurement system. Matt will demonstrate HUD image quality tests using Radiant's TT-HUD software module.
