Abstract
We have been developing direct fringe printer that can output holographic fringe on a photosensitive material. The pixel pitch of the printer is 0.44 micro-meter and the printing speed is 3 gigapixels per hour. Although the speed is faster than that of other printing methods, more speed is desired to print over 100 gigapixels holograms. In this paper, we use high power laser to reduce the settling time that is required to eliminate vibration after a stepper motor movement. Some other improvements are also discussed.
