ABSTRACT:
Illumination of the full moon has been adapted for photographic determination of spatial distribution of energy in the focal region of a faceted paraboloidal dish concentrator. The observed flux distribution is shown to be represented by the composition of two Gaussian distributions whose

peaks coincide in the focal plane and are displaced apart in other parallel planes. The expression for the intercept factor as a function of aperture size is derived. Sample computational results are presented. The procedure outlined is particularly important in design of receivers/absorbers for point focusing systems whose optical characteristics and manufacturing tolerances are difficult to be modelled mathematically.
