"The purpose of this thesis is the drawing of a comparison between the use of the colored filters, which are normally employed in the multiplex aeroprojector by various mapping agencies throughout the country, and the use therein of Polaroid filters. The filters in the aeroprojector serve to break the projection of a stereoscopic pair of photographs into two impressions which are viewed separately by each eye of the observer, thus providing the main requirement for the observance of a three-dimensional effect. this stereoscopic effect is utilized in the multiplex plotting machine for the delineation of contours...In order to form a suitable foundation for the research to follow, it has been deemed worthwhile to include several chapters at the beginning of this thesis which deal with such subjects as the fundamentals of photogrammetry, the use of the multiplex aeroprojector, the principles of stereoscopy, and the theory of light polarization"--Preface, page ii-iv.
