Photonics West and Electronic Imaging
Join us in San Francisco for the upcoming conferences
We look forward to starting the new year with two of our favorite conferences, SPIE Photonics West (January 28-30) and the Electronic Imaging Symposium (February 2-6). Both will take place in San Francisco. At the Photonics West, we will exhibit at the Nynomic Group booth with many other Nynomic companies.
At Electronic Imaging, CEO Dietmar Wueller will be teaching a short course with Eric Walowit on “Production Line Camera Color Calibration.” CTO Uwe Artmann will be teaching two short courses on “Measurement and Calibration of Image Quality KPIs” and “Camera Noise Sources and its Characterization Using International Standards.” He will also give a talk on “Extending the Noise Equivalent Quanta (NEQ) for Dynamic Range Measurement in Imaging Systems.”
We look forward to seeing you all there!
EMVA 1288 measurements
Machine vision camera measurements using the AEON camera calibrator
The AEON Camera Calibrator (ACC) is a modular optical system designed to test machine vision cameras based directly on the measurement parameters outlined in the EMVA (European Machine Vision Association)1288 standard, including linearity, noise, sensitivity, spatial inhomogeneities, and dark current.
The ACC is available in two sizes, one designed for standard sensors and another capable of handling sensors with diagonals up to 80 mm. It utilizes adjustable LED light sources and evaluation software. The authors of EMVA 1288 have used this solution to validate the standard.
EMVA 1288 will soon be adapted to an ISO standard. ISO 24942 is currently under development, with Dietmar Wueller leading the initiative.
Flexible illumination for transparent charts
Using the LE7 for transparent test chart
The LE7 lightbox uses iQ-LED technology to generate custom spectra in a 380 – 820 nm spectral range. We use the LE7 every day in our iQ-Lab to illuminate transparent test charts, e.g., OECF charts, uniformly.
We also offer a LE7 VIS-IR version, which expands the spectral range from 380 – 1050 nm for testing in near-infrared (NIR) situations. LE7-E is another version that can create a dynamic range up to 1:100,000. Such a wide dynamic range expands the testing possibilities, especially in low-light scenarios.
Camera color calibration
Combining the LE7 lightbox and the camSPECS plate
Combining the LE7 uniform lightbox with the camSPECS plate (TE292) offers a powerful solution for camera color calibrations. The LE7 uses the spectrally tunable iQ-LED technology to allow you to generate custom spectra for calibrations. The camSPECS plate mounts all interference filters onto one "test chart" to quickly measure spectral sensitivities using a single image. We offer a standard, XL, and IR version of the camSPECS plate.
iQ-Lab: Automotive image quality testing
Using innovative test methods to evaluate the IEEE-P2020 KPIs
Our iQ-Lab is at the forefront of automotive image quality testing. As part of the IEEE-P2020 working group, our lab engineers have assisted in developing the P2020 standard, which defines test metrics for automotive image quality performance. These metrics include contrast transfer accuracy (CTA), modulated light mitigation probability (MMP), and contrast signal-to-noise ratio (CSNR), among others. We can test automated driver assistance systems (ADAS), driving monitoring systems, and other in-cabin applications.
Our iQ-Lab uses advanced testing equipment, such as the Versatile Light System, to test the metrics according to P2020. Our lab has also developed the camPAS (Camera Performance for Automotive Systems) test to provide independent and objective test results to camera and sensor manufacturers and component suppliers as a neutral third party.
Contact the iQ-Lab to set up a camPAS test using your development specifications.
