21 January 1985 Devices For Measuring MTFs In The Infrared
Author Affiliations +
MTFs are usually computed indirectly from spread functions. The patterns used to generate these functions lead to certain problems in infrared systems. Square wave patterns have some advantages but also have some disadvantages. Sine wave patterns are useful but generally must be produced as area patterns. Various ways of using sinusoidal patterns are described.
