Paper Abstract

As a realistic visual task subjects had to recognize military vehicles out of six. alternatives. Percentages of correct identifications were determined at three different observation distances in order to interpolate the distance required for 50% correct, which is taken as a measure of performance. The scenery was simulated indoors by slide-projection in favour of better control of conditions and faster procedure. The slides were photographed at the location of an earlier field trial. The performance of a. portable, image, intensifier was measured, in this way as a function of luminance and contrast in object space. It ap-pears that recognition of the present set of objects is visually equivalent to the detec-tion. of a circular disk, and can be predicted from image quality data (displayed S/14, MTF) along that line.
