Abstract : An experimental investigation on rapid screening performance with transmitted imagery differing in scale, resolution (quality) and rate of presentation is reported. The operational objective was to find what degrees of screening throughness and accuracy can be expected for imagery of varying quality under different conditions. Examinees participating in the study were recent enlisted graduates of a U. S. Army intelligence school. Two examinees were randomly assigned to each of 48 experimental combinations to be tested. Resolution was systematically degraded to simulate transmitted imagery using a range of radio bandwidths and a range of film processor output rates. (Author)
