Abstract

Methods for designing substrate-mode holographic (SMH) optical elements are discussed in detail. These include techniques which account for the thickness change of a volume material during processing, and construction and reconstruction at different wavelengths. A method to reduce the angular sensitivity of these elements is also presented. Experimental results for components formed in dichromated gelatin with diffraction efficiency exceeding 95% and a FWHM (full angular width of the efficiency at half maximum) of more than 5° are given. Results for cascaded grating pairs are also discussed.
