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: An endoscope with a digital viewing system, such as a digital camera, with a housing having a longitudinal axis, with a lens attached to the housing and with an electronic image sensor positioned in the interior of the housing for converting a picture delivered through the lens into a digital format, characterized in that the image sensor is movable transverse to or out of the longitudinal axis. The movement of the image sensor facilitates focusing.
