Abstract

The objective of this research program was the development of the technology for the industrial manufacturing of HOEs for technical applications such as: holographic solar concentrators for utilization in photovoltaic energy conversion and solar photochemistry, and integrated holographic stacks for daylighting, glazing and shading in buildings. Some of the fabricated HOEs exhibit apertures in the order of 8 square meters. The accomplished technology facilitates the continuous fabrication of the holographic films on glass or plastic substrata. The standard holographic material we use for the fabrication of HOEs is dichromated gelatin (DCG) on glass or plastic film (PET) substrata. The dichromated gelatin layer could be prepared with different compositions to accommodate the desired exposures and chemical processing procedures. At present we manufacture holographic plates on glass substrata in sizes of up to 1 meter square. The holographic film on plastic substratum is 20 cm wide and could be made in lengths of hundredths of meters. The inexpensive fabrication of such large formats is attained by automation of the entire process: film manufacturing, hologram copying, development and test. We present in this paper the design considerations and the developed manufacturing procedures. These comprise the fabrication of large format reflective holograms for concentrating mirrors and the copying of transmissive holograms, such as gratings and lenses, using in-plane contact copying in checkerboard arrangement or rotating drum continuous copying onto an endless plastic film.
