Subsequent to publication the related proceeding papers will be listed on the Impact page.

The "Standardisation of luminance distribution measurements for assessing glare and obtrusive light using High-Dynamic-Range imaging systems" was presented by Constantinos A. Bouroussis et. al as a poster at the Scientific Conference on the Future of Metrology "From units to the universe - future revolutions in metrology" during the Celebration of 150 Years of the Metre at the BIPM in Versailles, France, in May 2025.

By examples from the field-measurement session at the LED-catwalk (LED-Laufsteg) of TUB, a street installation for research studies, the joint research project HiDyn and our approach for a "verification of luminance measurements of a street lighting scene using different configurations of luminance meters" was presented by Johannes Ledig et. al as a poster at the conference Licht 2025 in Oldenburg in March 2025. This includes spot-luminance meter, HDR imaging luminance measurements in different device configurations, and the high-contrast reference light source.

During the "Source de référence pour l'imagerie HDR de la luminance" was presented at the Conférence annuelle CIE France 2025 France.
