Abstract

A method to study the solar flux distributions of the solar images reflected by mirrors with different dielectric thicknesses is proposed in this paper. An optical scanner, also known as a flux mapping system, capable of acquiring the flux distribution pattern of a light source in a two-dimensional flat surface, has been designed and constructed. The optical scanner can measure the profile of flux distribution at reasonably high resolution with fewer photo-sensors with a fast scanning speed of several seconds. The real time measurement results of solar images projected by mirrors with dielectric thicknesses, i.e., 3 mm , 4 mm , 5 mm and 6 mm , have been performed to analyze their surface qualities.
