Abstract

Cathode-ray tube evaluation is becoming increasingly important in connection with the prediction of overall performance for systems incorporating an imaging display. Modulation transfer function has been measured by a method which takes account of the basic non-linearities of the crt and also offers improved accuracy by reducing the effects of phosphor screen noise. Two tests for crt internal veiling glare are discussed. Standard test conditions, which have been successfully used for a wide range of displays are described for both mtf and veiling glare. A contrast index is employed to indicate the extent of nonlinearity in the display transfer characteristic, and the paper also discusses briefly the use of generalised drive characteristics and limiting contrast curves as a supplement or alternative to modulation transfer function for definition of display performance.
