Detection theory [SEP] point in time
than the same sentry in peacetime due to a lower criterion, however they might also be more likely to treat innocuous stimuli as a threat.
Much of the early work in detection theory was done by radar researchers. By 1954, the theory was fully developed on the theoretical side as described by Peterson, Birdsall and Fox and the foundation for the psychological theory was made by Wilson P. Tanner, David M. Green, and John A. Swets, also in 1954.
Detection theory was used in 1966 by John A. Swets
definite (or "absolute") position to the object, and to say that the object is localized at a point in space. 
This is not what is found in quantum theory, however. For instance, the detection of light is described by the measurement of one-photon states. From a general property of Fourier transforms, the wave packet at a given time formula_17, with a spectrum width formula_18, indicates that the detection of an event can no longer be localized to a specific point in space — i.e.
