Abstract:
Four laboratory experiments were conducted to measure the television system resolution degradation caused by motion of the scene being viewed. A closed-circuit TV system was used, which consisted of a Cohu 3100 TV camera and a Conrac RND 9-inch monitor P-4 phosphor. The system viewed Landolt C, square-wave grid, and vehicle targets moving through the field of view at various velocities. The ability of human observers to detect the pattern detail was measured as a function of directions of motion, pattern size, pattern orientation, and pattern velocity. Data are presented which show the degradation in resolution as a function of these variables. The report includes a section on application of the data to electro-optical system design. Target identification abilities measured in the laboratory under both static and dynamic viewing conditions are used to estimate the raster line number, sensor field of view, and display size required to insure satisfactory human operator performance.
