Feasibility of Spiral and Radial Disc Method of Correlogram Scanning

摘要

The results of the study indicate that the ratio of phototube signal output-to-phototube noise, (S/N), calculated for average values of system parameters, is too small to be useful. Comparing signal current, dark current, and noise current, it is seen that the signal is approximately 2-1/2 times the noise, while the dark current is relatively negligible. Included are graphs (Figures 6, 7, 8) which give the interrelationships between the various parameters which influence the signal-to-noise ratio. If it is desired to compromise between any of these parameters to obtain a workable S/N, the curves will provide an estimate of the results to be expected. (Author)
