Chapter 12:
Human Visual System MTF and Threshold Contrast
Abstract
In the study of the behavior of optical systems it is essential to know how the human eye interacts with the output of those systems. The ultimate quality of an image depends directly on the modulation transfer function (MTF) and on the threshold contrast function of the human visual system. These also determine the optimum distance of the observer from the display so as to view a target of given size (Exercise 12.4). To begin to understand these, a knowledge of the physiology of the eye is essential.
