Paper Abstract

The high level of spatial uniformity in modern CCDs and other array detectors make them excellent devices for astrometric and navigational systems. However, at the level of accuracy envisioned by the more ambitious projects, current technology produces devices with significant pixel registration errors. This paper describes a technique for measuring relative pixel positions to an accuracy approaching 0.001 pixel. The technique has been applied to WF/PC II CCDs which are shown to have 500 nm step-and-repeat errors.
