Abstract
A method and a device for determining the rectilinearity of guide rails wherein a guide rail is oriented substantially parallel to a reference axis. At least one light beam is emitted along the reference axis by a light source and is detected by a light detector. When the light source or the light detector is displaced along the guide rail, warping and twisting of the guide rail can be detected as changes in the spacing between the guide rail and the reference axis.
