Abstract

An individual desires that information be presented to him in a manner consistent with his conditioning. This project was designed to meet this human need in one area, that of viewing in three-dimensions. A great deal of information gathered by various mechanical/electrical devices is obtained in its orthogonal form. These orthogonal signals can be related to the orthogonal projections in a cartesian coordinate system. If in some manner these signals could be related for visual purposes (in a manner much like our eyes do), it would be possible to use two two-dimensional figures and a stereo-dimensional object exists. To obtain this end, an adequate method for display and storage must be developed.

The problem of display is primarily one of finding a method of translating the three orthogonal components into two-dimensional images and feeding the proper representation to each eye. Combining the components is merely a matter of relating the image to these components in a mathematical manner. With a mathematical model, a program can be developed for the Analog Computer. The output can be fed to a display apparatus of some sort from which the proper images can be delivered to each eye.

Storage is desired for two reasons. One, it is often useful to be able to store the three orthogonal signals to view at a later time. Secondly, some signals have a frequency much too low to produce a solid trace for live viewing. To increase the frequency calls for recording the signal several times at different speeds. As the recorder by itself has severe limitations, it is necessary to use indirect methods to put information on to and take information off of the recorder. One of these methods, amplitude modulation, was the subject of a great deal of investigation. Other methods were also investigated as to their usefulness.
