Abstract: A device for detecting the profile of the rolling surface of a rolling body, in particular a tread of a tire for a vehicle includes a light source and an optical assembly configured for processing a first light beam emitted by the light source. The first light beam is a planar light beam having a divergent course, and the light source is configured for the emission of the first light beam towards the optical assembly. The optical assembly includes at least one first refractive member configured for collimating at least one portion of the first light beam incident thereon into a measurement beam that is directed towards a measurement section of the device to impinge upon the rolling surface.

Abstract: A detecting system for rail vehicles having at least one sprung rigid structure, for instance a bogie frame, and two axles, comprises photosensor position-detecting means applied to the structure and adapted to detect typical geometrical characteristics of the track and the relative position between the axles and the rails when the vehicle is running along the track and to supply electrical signals which are indicative of such geometrical characteristics and such relative position, and displacement detecting means also applied to the structure and adapted to detect relative displacements between the structure and the axles and to supply electrical signals indicative of these displacements. Electronic acquisition and processing means of these electrical signals provide a monitoring related to the configuration of the track and to the dynamic attitude of the structure and of the two axles.
