In this book the threshold of the human eye is investigated from a statistical point of view, and the effective spectral quantum efficiency of the eye is compared with that of technical devices employing opto-electronic photoemissive image detection by the present state of the art. Conventional light flux and energy units are converted into dimensions directly expressing the number of quanta involved, thus providing an easier comprehension of the statistical problems and limitations.
