Paper Abstract

The function of holographic optical elements in daylighting applications is to redirect sunlight from the immediate window area into the rear of a room in order to illuminate the darker regions and to reduce glare. A prerequisite for the successful application of holograms in daylighting systems is the solution of the problems of white light diffraction and of uniform holographic properties across a large aperture. This paper presents theoretical and experimental investigations of these two problems. It will be shown that white light diffraction is possible and that uniform diffraction efficiencies over large apertures are attainable.
