Patent ID: 8358423

Claim:
Method for non-contact measurement of an offset of the functional components of a guideway of a magnetic levitation train driven by a linear motor by at least one optical triangulation system movable alongside the guideway, comprising the steps of: providing a sensor system of at least two triangulation sensors, fixedly mounted on a movable carrier and geometrically displaced, for each measuring device for the functional components; moving at a determinable speed the at least two triangulation sensors along the guideway and, when doing so, operating the at least two triangulation sensors alternatingly as a measuring sensor and as a reference sensor with a radiation source in the ultraviolet, visible or infrared spectral range, wherein the diffusely reflected light is detected at a certain observation angle and the position of the light impinging on the measuring sensor is used for offset determination, and a sensing rate for detecting the measuring points in a grid of <1.5 mm is used.
