It points directly to the objective, quantifiable physical energy of the continuum of phenomenal consciousness as the presently unrecognized fifth fundamental force. Holography refers to the information storage process. The laser is the coherent light source that makes contemporary holography possible. Nevertheless, this bright flash of holographic lightning may usher in a new day that illuminates the cosmos beyond the purview of either Plato or Aristotle. They effectively record only the information contained in the limited optical region, the visible light region, of the electromagnetic radiation spectrum.
Light travels through a given medium in a wave-like form.
To capture the information contained in the incident light waves, photographic film with an appropriate emulsion speed records the pattern of light obtained from an object or scene of interest. A hologram records both the intensity and the phase relationships of the incident light waves. Thus, according to present scientific understanding, a hologram captures the whole message contained in the incident light waves of interest. A laser provides a coherent light beam which is used for both purposes. A beam splitter, an optical device that divides the coherent beam into two parts, is placed directly in the laser beam.
