Paper Abstract

A rapid procedure is outlined that permits accurate alignment, focus, and scaling of imagery at two separated locations in an optical system. The moire pattern formed by pairs of identical gratings permits the full image pupil to be observed and adjusted. Alignment and scaling can be adjusted to an accuracy of the order of the grating's fundamental spacing.
