摘要： A method and arrangement for transmitting radiation emitted by LEDs operated in pulsed operation via at least one optical waveguide, wherein a first optical waveguide having first and second coupling surfaces is assigned to each LED, the first optical waveguides are in each case aligned, by their first coupling surfaces, with an assigned stationary LED, the second coupling surfaces are arranged on a closed path and a coupling surface of a second optical waveguide is assigned to the second coupling surfaces. In order that a high light power can be coupled into the second optical waveguide by means of the LEDs, it is provided that the second optical waveguide, in accordance with the clocking of the switched-on LEDs, can be aligned with the second coupling surface of a first optical waveguide from at least one switched-on LED.

摘要： The invention relates to a method for three-dimensional shape measurement of a body or of a part thereof, in particular of a dental object such as a model, by scanning non-contact distance measurement using an optical sensor device comprising a beam source, where the shape of the body subjects reproducing areas to a beam at various incidence angles (impinging beam), and the reflected beam (measuring beam) is measured, with the body being adjusted relative to the optical sensor device. To permit measurement with high precision of the body and undercuts thereof, without tilting being necessary, it is proposed that for shape measurement of the respectively measured area the beam (measuring beam) reflected therefrom, which describes an angle α to a surface normal corresponding to the respective area, is taken into account, said angle being equal to or smaller than a predefined critical angle αGR relative to the surface normal
