Empirical Laws for Brightness Discrimination Thresholds as a Function of Time Between Two identical Flash Increments,

Abstract

Visual displays of radar, sonar, and other weapons systems devices provide signals that vary in their temporal characteristics. Typically, these temporal characteristics may be manipulated by the operator of the display device to achieve optimal detection or identification of signals. The aim of the research reported here is to determine how two successive visual signals, displayed upon various background fields, interact to influence detectability. The general laws that were devised to describe the results of the experiments have application to any display in which two temporally-spaced signals occur. (Author)
