Computer algorithms for the encoding of electron-beam written holographic optical elements (HOEs), previously developed on a large main-frame computer, have been ported to a desktop computer and upgraded to use a more prevalent a-beam lithography system. Hardware requirements, encoding methods, and space-bandwidth limitations are discussed. Inasmuch as the inefficiency of the a-beam pattern description language in describing non-repetitive, non-rectilinear hologram patterns remains the prime limiter of hologram space-bandwidth product, the transition to a desktop computer has been accomplished without penalty.
