Holographic Imaging
Chapter One
Holograms and Perception
Provoking Spatial Perceptions
Any discussion of three-dimensional images properly begins with a
discussion of human vision, and the mechanisms by which we
perceive spatial relationships, including shape, position, distance,
and motion through space. These can be roughly grouped into three
types, depending on whether they are driven by (1) single-eyed
(monocular) vision or (2) properly-combined two-eyed (binocular)
vision, and by whether (3) they are stimulated by static or moving
images (or perhaps the motion of the observer) in various
combinations. A thorough discussion goes beyond the scope of this
book, although we will revisit the topic in later explorations of the
design of holographic images. Many references are available that
explore these issues in detail (e.g., Okoshi (1976), Patterson &
Martin (1992)).
For our purposes, we will concentrate on the triangulation of
point sources by binocular vision as the primary stimulus, "cue,"
for spatial vision. Implicit in this are other cues arising from mot ... read full excerpt from Holographic Imaging ebook
