Abstract
The purpose of this paper is to describe a new procedure for evaluatin g the modulation transfer function (MTF) of an infrared focal plane ar ray. This technique is based on the generalized line spread function m ethod in which the MTF is derived from the image of a periodic target consisting of thin lines. The self-imaging property of this kind of ob ject is used to project the target on to the tested focal plane array.
