Popis: An optical measurement for radiation concentrators is proposed. A Lambertian light source is placed in the exit aperture of the concentrator. By taking pictures of the concentrator as seen from a remote location one gets the transmission patterns which carry the information of transmission with the four-dimensional resolution of the phase space of geometric optics. By matching ray tracing simulations to the measurement, one can achieve detailed and accurate information about the geometry of the concentrator. The reflectivity can he inferred by very simple means with 2% accuracy. This method has the potential to provide a handy tool to get automatically all optical information about a real size concentrator in situ.
