Scientific American (December 1974, Vol. 231, No. 6) Single Issue Magazine – January 1, 1974. See all formats and editions Hide other formats and editions.The final chapter is devoted to the subject of holography. The techniques developed by Gabor and by Leith and Upatnieks are considered in detail and compared. Both thin and thick holograms are treated. Extensions to three-dimensional imaging are presented. Various applications of holography are described, but emphasis is on the fundamentals.Table of contents for issues of Scientific American Last update: Sat Jul 6 17:15:17 MDT 2019 Volume 262, Number 1, January, 1990 Volume 262, Number 2, February, 1990 Volume 262, Number 3, March, 1990 Volume 262, Number 4, April, 1990 Volume 262, Number 5, May, 1990 Volume 262, Number 6, June, 1990

According to the holonomic brain theory, memories are stored within certain general regions, but stored non-locally within those regions. This allows the brain to maintain function and memory even when it is damaged. It is only when there exist no parts big enough to contain the whole that the memory is lost.Holograms of naturally illuminated objects are synthesized in two steps. A stereoscopic camera technique is used to record the objects' parallax qualities in white light; this photographic information is transformed into a hologram with coherent light. The image quality is excellent, and the method seems practical for making full‐color reconstructions using stereoscopic photographs taken.Transmission holograms, originally made by Leith and Upatnieks, require monochromatic light (usually a laser) to view the image, otherwise viewing in white light causes severe chromatic aberrations, whereas holograms produced by Denisyuk’s method can be viewed in light of a broad spectral range.

Abstract. Holography is a technique producing a three-dimensional picture of a real physical object. A hologram is a recorded interference pattern between light coming from an object (the object field) and light coming from a suitable reference source (the reference field).The very early laser transmission holograms demonstrated by Leith and Upatneiks in the USA [1], presented a dichotomy for display. Viewing their first holograms required laser light to be directed through the holographic plates using the same path taken by the original off-axis recording beam.Juris UPATNIEKS. 1960.-1965.gados J.Upatnieks kopā ar E.N.Līsu (Leith) izstrādāja un eksperimentāli pierādīja principiāli jaunu fizikālās optikas metodi hologrammu uzņemšanai, kura novērsa divu attēlu problēmu agrāk publicētajā Gabora metodē
