Abstract

In 1971, under the auspices of the Dutch Ministry of Defence, a committee started with a standard for the measurement of the MTF of image forming equipment. In a short time a reasonable and workable standard was produced that covered optical and electro-optical systems. This standard was far from perfect but it did contain so many useful starting points for the working out of an improved standard that it was presented to a NATO commission which had the task of preparing an OTF standard for the NATO countries as a whole. The paper deals further with some interesting aspects of the OTF and with problems encountered in OTF standardisation when non perfect imaging devices that have veiling glare, non isoplanatism or a restricted linear range are considered.
