<p>PURPOSE: An optical waveguide tube is provided to facilitate the design and manufacturing. CONSTITUTION: An optical waveguide tube has two parabolic mirrors (100,200) which have a parallel optical axis and which face to each other. The light source which is placed on a focus F1 of a first parabolic mirror precedes the emitted light to an optical path which is dispersed to various directions, and converges to an optical detector which is placed on a focus F2 of a second parabolic mirror. The first parabolic mirror and the second parabolic mirror are indicated in a constant equation in a coordinate system, respectively.</p> |
