PRELIMINARY RESEARCH ON MATHEMATIC MODEL OF EYE'S ADAPTATION LUMINANCE

摘要

CIE recognizes the need for a comprehensive research program to develop a fundamental model of discomfort glare as its Top Priority Topics of research strategy. One drawback for current glare evaluation models is their faults to take average environment luminance as an indicator for visual adaptation, which means that luminance distribution and glare sources are not taken into account. There is no doubt that the measurement or estimation of adaptation level in natural environments is practically important. IpRGCs act as a photon counter in the same way than a light meter in a camera, which project to the olivary pretectal nucleus (OPN) to control pupil light responses. In this research we will establish a facility to simulate different luminance distribution with a diameter 2.4m LED semi- sphere screen, and monitor the pupil diameter with eye tracker. A preliminary model will be developed on the basis of collected data.
