Figure 6.1 A long-exposure image with several short images superimposed.
Figure 6.2 Components of a long-exposure image, showing the contribution of im-
age motion. The normalized aperture is in units of D/r 0 and the image size is normal-
ized in λ /r 0 . The individual curves are A, the diffraction-limited case; B, image motion
only; C, the short-exposure case; and D, the seeing-dominated case.
