Claim 8:
9. A method of generating a hologram from a three-dimensional image data set, the three-dimensional data set being separated into a plurality of two-dimensional image layers at different image planes, comprising:
a) performing a Fourier transform on each image layer to provide a transformed image layer,
b) applying a focus factor to each transformed image layer,
c) applying a pseudo-random phase factor to each transformed image layer, and
d) combining the transformed image layers to form a holographic sub-frame,
e) repeating steps (c) and (d) for a plurality of iterations, applying a different pseudo-random phase factor to the transformed image layers in each iteration to form a plurality of holographic sub-frames; and
f) driving a spatial light modulator with the holographic sub-frames in rapid temporal succession and illuminating the spatial light modulator with a coherent light source.
