AB - In three experiments (N = 5, 5, and 6) CRT bias and ambient illumination were varied jointly, and pip visibility thresholds were determined. It was concluded that "... there is an optimal CRT bias (or range of biases) at which radar targets are most visible; and ambient illumination can be as high as 0.1 footcandle without loss. The decrement produced by working in darkness and at bias values close to VRI (Visual Reference Intensity), as against optimal conditions, is of the order of 10 db. of signal voltage. This can mean... a loss in radar range of up to 25 percent."
