Abstract:
1. A measuring apparatus for determining the material strength of an object, comprising: a reference object of a predetermined thickness between a first reference main surface and a second reference main surface, wherein the first reference main surface is facing a first distance measurer and the second reference main surface is facing a second distance measurer; wherein the first distance measurer is implemented as light-slit measurer for simultaneously determining a first distance between the first distance measurer and a first main surface of the object facing the first distance measurer as well as a distance between the first reference main surface and the first distance measurer in measurement direction; and wherein the second distance measurer is implemented as light-slit measurer for simultaneously determining a second distance between the second distance measurer and a second main surface of the object opposing the first main surface as well as a distance between the second distance measurer and the second reference main surface in measurement direction; and an evaluator for determining the material strength of the object between the first main surface and the second main surface by using the first distance, the second distance, the predetermined thickness, the distance between the first reference main surface and the first distance measurer, and the distance between the second reference main surface and the second distance measurer.
