Abstract

This paper proposes an instrument allowing the accurate characterization of the energetic distribution of a given source at a distant plane positioned at will. This is achieved by measuring the light pattern leaving the source by applying deflectometric techniques and photometric measurements, and then applying raytracing algorithms in order to propagate this distribution to a distant plane. The techniques allow a very compact setup, and a prototype of the optomechanical system has been implemented and tested. The system is intended to substitute the photometric tunnels now in use for testing, for instance, automotive reflectors.
