Abstract : The objective of the program was to design and develop two (2) experimental prototypes of a volumetric threedimensional display utilizing point-light-images generated by cathode ray tubes which are seen by an observer located in the real image field of a parabolic and plane mirror. Various approaches of image combining such as time-sharing and light-sharing were investigated. The investigation resulted in the verification of the feasibility of the 3-D display concept. Both light-sharing and timesharing of multiple image presentations are possible means of reproducing images in three dimensions. The choice of method is predicated on the specific application. The utilization of three dimensional presentation is restricted only by the quality of the data received for presentation, quality of the optic-electro-mechanical system and functional space. Recommendations for additional investigation as a continuation of this study are: (a) Investigation of vision threshold and fusion frequencies below 5 microsecond regime and (b) Continuation of the development of uses of cathode ray tube image production technique to present 3-D information with time and/or light-sharing methods.
