Background & Innovations in True Volumetric 3D
|Welcome to the world of Volumetric Imaging where we attempt to create the practical "crystal ball" of the soothsayers -- a volume in which all space and time may be displayed at your command. We have not been alone in this quest but have followed the path of the early pioneers and visionaries. Gauge your analysis by the curl of your thoughts as we venture into the color and charm of the chromosphere.|
|The Early Pioneers|
|One of the earliest
functional volumetric imagers was this excellent design
by Schipper from 1960. It set the standard for the
rotating screen technologies which were to follow --
including x-y addressing, a speed control motor, and a
At the time, high speed light emitters were extremely costly serious hindering the development of large prototype systems for the study of the human visual system response.
|Ketchpel's 1960 Cathode Ray Tube Imager represents a major step in the integration of television technology and volumetric imaging. Although the electron beam steering technology was at its infancy he clearly anticipated systems which would embody complex, computer-controlled single and multiple guns within an evacuated enclosure.|
|Moving to Solid State Systems|
|The Swainson Laser Imager in the mid 1970's represents a conceptual breakthrough in volumetric systems. For the first time, the concept of a volume comprised of a homogeneous media and illuminated by intersecting beams was proposed. Swainson enumerated a broad spectrum of excitable composites.|
|n 1990, Eastman Kodak researcher, E.L. Morton, devised a method for eliminating the defocusing effect of the change in optical path length in the helical screen volumetric imagers.|
|Digital Volumetric Systems|
|As a student at MIT in the late 1970's,
Edwin Berlin developed a innovative approach to data flow
problem which had been constraining early systems. He
placed the display electronics on a rotating matrix of
light emitters and used a high-speed optical link to
connect to the outside world.
The technology was exiled from MIT by myopic visionaries.
|Volumetric Imaging Projects|
|The Volumetric Matrix Imager Model 200|
|The Model 200 is a 18" diameter x
36" high Matrix Imager System. All the computational
components are contained within the enclosure of aluminum
This Imager was designed for lower cost experimentation and demonstration. It found success as a research platform in academia and government as well as in the "high art world" when Jenny Holzer chose it as the centerpiece for her Siddeutchse Zeitung exhibit "Lustmord" in 1994. In addition to wide visibility in the European press, the Imager was included in a Sunday New York Times Art Section article on her exhibit.
