Abstract
The flexibility of computer-generated holograms is used to advantage,
e.g. in optical filtering, laser beam scanning and beam splitting, and
in test of aspheric lenses. However, storage of information by CGHs
either for computational use or application as a display seems a
valuable goal due to the inherent advantages of holography. Problems
arise in the software as well as in the hardware, especially
concerning the overall handling time. Usually it is kept minimum by
use of the FFT, even if this restricts the object to be a 2-D
transparency.
