title: Images of truncated one-dimensional periodic bar targets in aberration-limited optical systems.
abstract: This paper deals with the properties of the images of truncated one-dimensional periodic bar targets formed by aberration-limited optical systems. Attention is directed to the problem of determining how many bars are required at a given spatial frequency in order to obtain an image which closely approximates that for an infinite-chain periodic bar target. Numerical calculations are carried out for the case of an aberration-limited, glancing-incidence x-ray telescope.
