Abstract
We fabricated a relative large holographic optical element (HOE) with same course of production of the DOE. To make the some persons who are situated on the long distance recognize image data using the hologram, the hologram must have bright image reconstruction ability and a high SN ratio. Because it supposed that the distance to an object was long, we adopted a computer-generated hologram (CGH). Also, it used an image-setter and a laser direct-write lithography system that have the feature of high-resolution drawing, high-speed drawing, and a high accuracy positioning system, for the making of hologram. The large character images of object have been successfully displayed on long distance by setting up CGH.
