Abstract : A basic requirement in the design of television subsystems for visual simulators, is knowledge of the minimum information content and rate to be presented in the final display. The results of an experimental research program and statistical analysis indicate that the image height of a naval vessel must contain at least five television resolution lines and subtend no less than 6.5 minutes of arc. A pessimistic figure of six lines is used in an example to demonstrate the television channel bandwidth needed for a periscope simulator visual display. (Author)
