Device for determining modifications of the mutual position of two machines or parts of machines which are separately mounted at a certain distance from each other with respect to a given starting position in a right angle spatial coordinate system. Thereby, a high operation efficiency and a high measuring precision together with low construction costs and a reduced sensitivity to perturbations, as well as a direct perceptibility of orientation errors with respect to the parallel displacement and the angular displacement are obtained. This is effected by using an orthogonal reflector prism and a light emitter for each of the three axial directions of the coordinate system where a neutral parallel and angular displacement is to be observed, the reflector prisms and the light emitters being mutually fixed to the machines, respectively to the machine parts. |
