An apparatus for determining the position of an object comprises a light source positioned in relation to the object so that at least one collimated beam is issued from a particular positon on the object and bearing a fixed and definite geometric relationship to the sought position; a fluorescent foil or plate is positioned in relation to such object such that a particular spot is stimulated by that collimated beam which then provides the fluorescence; a plurality of fiber optics are arranged such that one end of each fiber optics is placed on a particular geometric pattern to receive radiation from the stimulated spot while the respective other end of each fiber optics is arranged in a similar but smaller scale geometric pattern as the first ends are and in relation to a detector that provides an electrical signal representing the position of the object.
