Abstract
A method for determining three orientational degrees of freedom of a cube-corner retroreflector by obtaining with a photosensitive array an image of a three straight marks on the retroreflector and, with a programmable control device, taking a two-dimensional transform of the image and determining the three orientational degrees of freedom.
