Abstract :
Quantitative results were obtained on minimum detectable signals and minimum separation between two targets as a function of the following variable factors: video gain, c.r.t. bias, signal clipping, light-source intensity, type of diffraction screen, and position of the operator. The projection (PPI), using a dark-trace tube, appeared to be 1 db worse than a standard 5-inch PPI, when each instrument was operated under its optimal conditions.
