Abstract
The Special Devices Division of the Navy's Office of Research and Inventions conceived the idea of projecting the image of a solid model on a screen. For this particular trainer it was desired to project an airplane model on a spherical screen. Moreover, the image itself had to be movable so as to be positioned at any point on the spherical screen. Among the many problems which had to be overcome were depth of field, as in microphotography, the level of illumination, as in all epidiascopes, and finally the wide range of magnification. Many optical combinations were computed and tested, as well as a variety of light sources and condensing designs. The most suitable combination was adopted and built into the first model.
