This article describes the luminaire's near field photometry measurement facility developed at CSTB Labs. It is based on the acquisition of couples' image/irradiance at various positions on a hemisphere surrounding the light source to be measured. A storage structure and an interpolation scheme for the data are presented. Finally, a generic interface for the exchange of near field measurements is proposed. This version of the paper is reduced for the conference pre-print so if available, the electronic version should be preferred.
