1. The pattern produced on a photosensitive medium that has been exposed by holography and then photographically developed.
2. The photosensitive medium so exposed and so developed. Also called holograph.
hologram (hol'e-gram`) noun
A three-dimensional image record created by holography. The hologram consists of a light interference pattern preserved in a medium such as photographic film. When suitably illuminated, it produces an image that changes its appearance as the viewer changes viewing angle.
holography (ho-lòg´re-fê), method of reproducing a three-dimensional image of an object by means of light-wave patterns recorded on a photographic plate or film. The object is illuminated with a coherent beam of light produced by a LASER. Before reaching the object, the beam is split into two parts: the reference beam is recorded directly on the photographic plate, and the other is reflected from the object and then is recorded. On the photographic plate the two beams create an INTERFERENCE pattern, exposing the plate at points where they arrive in phase. When this photographic recording, called a hologram, is later illuminated with coherent light of the same frequency as that used to form it, a three-dimensional image of the object becomes visible and the object can be photographed from various angles. Color holograms are formed using three separate exposures with laser beams of each of the primary colors. In acoustical holography, a coherent beam of ultrasonic waves, instead of light, is used. The resulting interference pattern is recorded with microphones to form a hologram, which, when viewed with laser light, produces a visible three-dimensional image. Holography has been combined with microscopy to study very small objects; it also is used in industry for stress and vibrational analysis.
Apollonius of Tyana, writing as Hermes
Trismegistors, said "That which is above is that which is below." By this
he meant to tell us that our universe is a hologram, but he lacked the term.

"We can record essentially anything we want about any event and recall it later. There is a synthesis of all this, which leads to the discovery of the inner dimension, which may be thought of as a higher or lower dimension. The human imagination is the dimension beyond space and time, or it precedes all dimensions. At some level it has pointlike characteristics; that's why all this talk about the hologram, because it has the pointlike characteristics of new consciousness. It has all-at-onceness. Its everywhere-at-the-same-timeness has fascinated commentators."
"I suggest that it is much more useful to try to
make a kind of geometric model of consciousness, to take seriously the
idea o fa parallel continuum, and to say that the mind and the body are
embedded in the dream
and the dream is a higher-order spatial dimension. In sleep, one
is released into the real world, of which the world of waking is only the
surface in a very literal geometric sense. There is a plenum - recent
experiments in quantum
physics tend to back this up - a holographic plenum of information.
is everywhere. Information that is not here is nowhere. Information
stands outside of historical time in a kind of eternity - an eternity that
does not have a temporal existence, not even the kind of temporal existence
about which one may say, "It always existed." It does not have temporal
duration of any sort. It is eternity. We are not primarily
biological, with mind emerging as a kind of iridescence, a kind of epiphenomenon
at the higher levels of organization of biology. We are hyperspatial
objects of some sort that cast a shadow into matter. The shadow in
matter is our physical organism."

Carl Jung's 'Mysterium Conjunctionis' reminds us of the reality of the situation that ensues once the psyche is hooked into making the transference to the alchemical or saucerian goal. Jung, citing Gerhart Dorn, stresses that the materialization of the stone is only a prologue to the experience of the perfected self in a state of illumination. Jung wrote, "Though we know from experience that psychic processes are related to material ones, we are not in a position to say in what this relationship consists, or how it is possible at all. Precisely because the psyche and the physical are mutually dependent it has often been conjectured that they may be identical somewhere beyond our present experience."
Of what does this relationship consist? My own hunch, and it is only a hunch, is that an explicitly spatial dimension -- of a co-dimension inclusive of our continuum -- allows a hologram of other realized forms of organization, far distant, to become visible at certain levels of quantum resonance in the synaptic field. These levels have been damped by selection in favor of more directlyrelevant lines of information relating to animal survival. Evolution does not reinforce selectively the ability of an organism to perceive at a distance since such an ability has no selective advantage, unless the information it conveys falls upon the receptors of an organism already sophisicated enough in its use of symbols to abstract concepts for later application in different contexts.
Thus, these quantum resonances carrying intimations of events at a distance only begin to acquire genetic reinforcement once a species has already achieved sufficient sophistication to be called conscious and mind-possessing. The use of hallucinogens can be seen as an attempt at medical engineering which amplifies, for inspection by consciousness, the quantum resonance of the other parts of the spatial continuum holographically at hand. This experience is the vision which the UFOs and psilocybin impart: visions of strange planets, life forms, perspectives and societies, machines, ruins, landscapes. The hierophanies all unfold in a nunc stans that has all space -- standing in it -- like a frozen hologram. Thus, experimentation with hallucinogens by human beings and the rise in endogenously produced hallucinogens as one advances through the primate phylogeny could both be due to a slow focusing on the phenomenon of imagination. Imagination being the deepening involvement of the species with things beheld but not actually existing in the present at hand.

If we were to look closely at an individual human being, we would immediately notice that it is a unique hologram unto itself; self-contained, self-generation, and self-knowledgeable. Yet if we were to remove this being from its planetary context, we would quickly realize that the human form is not unlike a mandala or symbolic poem, for within its form and flow lives comprehensive information about various physical, social, psychological, and evolutionary contexts within which it was created.
