Abstract
A description is given of the architecture of a high resolution, photo grammetric image scanner. A sequence of steps is given to mutually ali gn a linear sensor, an objective lens, and a two-axis stage. The recom mended alignment sequence is supported by derivations from geometric o ptics. The overall system geometry is then verified by scanning and an alyzing a grid plate yielding RMS errors of 5 mum in X and Y.
