Proposed new type three dimensional display based on Discrete Fourier
Transform (DFT) is possible to produce rays in the natural world. The
DFT display has the following features Observation area is wide. Some
viewers are able to watch the display at the same time without special
glasses. Regenerated three dimensional images change with movement of
view point. For the purpose of increasing horizontal resolution of re
generated images, the demonstrator, combined two 10.4 inch XGA type TF
T-LCDs and two staggered slits, has been fabricated.
