Paper Abstract

The vague concept of "resolution" of a detector aperture (or of the source distribution in transmission imaging) is quantified in terms of an elementary signal discrimination task. The signal-to-noise ratio that characterizes performance of the discrimination task is obtained from statistical decision theory. Defining efficiency in terms of the square of this ratio, we find the uniformly redundant array to be 15 times as efficient as a simple open aperture or source of the same area for discrimination tasks when the objects are point-like. Otherwise, it is more efficient to use the simple large open aperture or source.
