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 stationary enclosure.

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.

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.

The technology was exiled from MIT by myopic visionaries.

In 1990, Volumetric Imaging licensed the patent and developed a low cost system which displays 1,000,000 voxels simultaneously.

The Model 200 is a 18" diameter x 36" high Matrix Imager System. All the computational components are contained within the enclosure of aluminum and polycarbonate.

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.

This Model Imager has found a place at SIGGRAPH 1994, trade shows and symposia for general advertising purposes.

The Volumetric Matrix HoloDeck Imager integrated our patented "out of the sphere" technology.
