Paper Abstract

This paper discusses recent progress in producing computer-generated holograms (CGH) of low spatial distoration and high space-bandwidth product. The CGH are drawn directly on electron-resist using an electron beam pattern generator which is intended for use in the production of integrated circuits with sub-micron feature sizes. This approach not only reduces plotting errors below those introduced by indirect writing methods, but also provides more than 106 distortion-free resolution points in a hologram of correct size. The quality of the CGH made by this process will be illustrated by an example in the testing of an aspheric surface.
