CIE Expert Tutorial and Symposium on the Measurement of Temporal Light Modulation

10-11 October 2022 | National Technical University of Athens, Athens, Greece

Temporal light modulation (TLM) causes visual perception effects such as flicker,
phantom array and stroboscopic effects. All of these issues can have adverse effects on
users of lighting products (such as performance and health), thus the accurate
assessment of TLM is fundamental to proper assessment of its effects on users.

To support the current understanding and to explore current research on this topic
the International Commission on Illumination (CIE) is holding an event that includes a one-day expert tutorial and a one-day symposium. This is hosted by The National Technical University of Athens (NTUA) and will be held at The Royal Olympic Hotel, Athens.

Event overview

The first day of this event features an Expert Tutorial on the Measurement of
Temporal Light Modulation (TLM). Experts from around the world will give lectures on
all aspects of measurement of TLM. An outline for the tutorial is available and the list of topics include:
• fundamentals of TLM and temporal light artefacts (TLA);
• CIE TN 012:2021 “Guidance on the Measurement of Temporal Light
Modulation of Light Sources and Lighting Systems”
• measurement of TLM;
• calculation of predictors of TLAs;
• estimation of measurement and calculation of uncertainties.

The second day of the event features a Symposium on Advances in Measurement of
Temporal Light Modulation. This one-day scientific symposium features contributed
papers on active research on TLM and TLA.

More information about this CIE event can be found on the event webpage.
