Abstract
An optical waveguide with a tubular or hose-like housing is provided, which is used in a high-temperature environment, such as, for example, in a burner. The housing has an input opening, an output opening and a center line extending from the input opening to the output opening. In the interior of the housing, transparent spheres are lined up along with center line. The light is guided on account of the refraction of a light beam upon entering and exiting from the transparent spheres.
Claims16
An optical waveguide, comprising:
- a tubular or hose-type housing which has an input opening, an output opening and a center line extending from the input opening to the output opening;
- and
- a series of transparent spheres in the interior of the housing lined up along the center line, wherein the housing is designed as a flexible hose and the spheres are spaced apart in the housing, and the guidance of the light takes place due to the refraction of a light beam when entering or exiting from the transparent spheres;
- a spacing arrangement extending from the input opening to the output opening which provides a spacing between the spheres, and
- wherein a helically wound projection is present as the spacing arrangement on the inside of the housing extending from the input opening to the output opening, with spacing of coils of the helically wound projection from each other being chosen so that the spheres are located between adjacent coils.
A burner, comprising:
- an integral optical waveguide having a tubular or hose-type housing which has an input opening, an output opening and a center line extending from the input opening to the output opening, and transparent spheres in the interior of the housing lined up along the center line, wherein the housing is designed as a flexible hose and the spheres are spaced apart in the housing with a spacing arrangement extending from the input opening to the output opening to provide a spacing between the spheres, and the guidance of the light takes place due to the refraction of a light beam when entering or exiting from the transparent spheres, and
- wherein a helically wound projection is present as the spacing arrangement on the inside of the housing of the integral optical waveguide extending from the input opening to the output opening, with spacing of coils of the helically wound projection from each other being chosen so that the spheres are located between adjacent coils.
