摘要:
A method and a device for the non-contact optical measurement of paths uses light of a monochromatic coherent light source (1) to generate a light spot (7) on the object (6) to be measured, having a diffusely scattering surface. An optical system (14) is provided to image the light spot (7) on a position-determining image recorder (10). A device (5) for deflecting the light beam (2) emitted by the light source through a small angle or offset is provided in the beam path between the light source (1) and the object (6).
摘要:
A method is for determining the axle geometry of a vehicle, wherein light of a given structure is projected onto a vehicle wheel, and the diffusely reflected light can be analyzed in order to determine the orientation of the plane of the vehicle wheel. Several lines of a laser light generated by means of one or several laser light sources are projected on the wheel, and one or several of these lines fades in and/or out in temporal succession. The reflected light is captured by means of one or several cameras.
