Abstract
Two dimensional Focal Plane Array imaging devices are widely used. We define an index of the image quality for such optical systems. To properly express the efficiency of such a system we need to know the fraction of the amount of light leaving the conjugate area in the object space which falls inside a given element of the image receiver. Expressions for this quantity are formulated in terms of the OTF, and since the OTF is a func don of spatial frequency we can separate the effects of the different spatial frequencies and see how they each contribute to the final intensity. In particular we can examine the loss of intensity due to the use of spatial frequency filters.
