Paper Abstract

The subject matter of this report is the presentation of an optimization technique developed for the design and manufacturing of a holographic lens solar concentrator. The emphasis is placed on the realization of a homogeneous diffraction efficiency distribution across the aperture of the holographic lens. The nature of the holographic process requires precise control of the mechanical properties of the gelatin layer such as moisture content, shrinking, swelling, hardness and elasticity, which specify the slant angle, the mean index of refraction, the spatial frequency and the amplitude of the refractive index variatrion. These parameters determine then uniquely the Bragg condition and the diffraction efficiency. The range of parameter variation is obtained from a large number of experimentally analyzed transmission gratings with spatial frequencies that are comparable to those expected across the aperture of the holographic lens
