Characterization of hologram elements (hogels) produced using specially
designed test pattern images provides more accurate information that can
be used to render images for use in hogel production. Once a test pattern
is selected, one or more hogels are recorded in a holographic recording
material using a spatial light modulator displaying the test pattern
image. Recorded hogels can then be played back to produce an image of the
test pattern. Characterization of this image yields information that is
used to select angles used to render oblique parallel projections of a
computer graphics scene. The rendered projections are then used to record
hogels that will produce images with reduced distortion.
