    摘要: The material thickness of extended objects can be efficiently determined using two distance measuring devices which project a strip of measuring light onto the object to be measured and operate as light section measuring devices. The first distance measuring device determines the distance from the first main surface of the object, and the second distance measuring device determines the distance from the second main surface of the object, opposite to the first main surface. Potential measuring errors caused by variations of the distance between the two distance measuring devices, resulting from vibrations or thermal deformations, are avoided by the fact that the strip of measuring light of the two distance measuring devices also sweeps a reference object with a pre-determined thickness, such that the thickness of the object between the first main surface and the second main surface can be determined with a high level of precision and speed, on the basis of the measured distances from the main surfaces of the object and from the reference object, and the pre-determined thickness of the reference object.
