Abstract

A new method of making computer-generated hologram (CGH) by electron-beam direct-writing is reported in this paper. Compared with conventional CGH fabricating method, the new method can improve the image quality of CGH obviously. In this paper, the comparative experimental results of two methods are given, and the effects of quantizing and coding errors on the signal-to-noise ratio of CGH are also analyzed theoretically.
