Abstract

Device for determining the position of a mobile element relative to another element on which a measuring scale has been fixed and which comprises an optical system for transporting an image of the scale to a reading plane and a reading device in this plane of said image of the scale, characterized by the fact that the optical system transports the image is a vehicle that works in expansion -1.
