Abstract: International standards require that VDU products should be flicker free to at least 90% of the user population. There have been many methods proposed to achieve this objective. However, it is extremely difficult to validate or compare data between the various methods because of the nature of subjective variability and the lack of a common quantifiable reference. This paper describes an objective flicker measurement technique that provides such a reference and also two subjective experiments designed to validate the measurement accuracy.!10
