Development Of High Efficiency Holographic Optical Elements

Abstract

In this report we present the up-to-date knowledge acquired in the design and manufacturing of inexpensive, high efficiency, holographic optical elements (HOE) such as focusing lenses, beam-splitters, lens arrays and integrated holographic optics for specific technical applications. One such application is the development and manufacturing of an integrated Laser-Doppler optics which contains several HOE. The holograms are generated in dichromated gelatin layers and exhibit very high diffraction efficiencies (98%). The resulting Laser--Doppler measuring volume is characterized by excellent optical quality and high S/N ratio.
