Suppose a number of X-ray pictures is taken of the same object, but from different directions. One typically likes to know to what degree the pictures determine the object and exactly when an object is uniquely determined. Replacing picture taking by projections, that is, images relative to specified mappings, these same problems are easily formulated for higher dimensions and even for abstract spaces. With this general framework, starting from an arbitrary but fixed collection of mappings, we study a new and very useful class of objects (sets) each of which is uniquely determined by its projections
