Abstract
A fluid conduit comprises an inner conduit configured for conducting a fluid, and an outer conduit circumferentially enclosing the inner conduit. The outer conduit's inner diameter is larger than the inner conduit's outer diameter, with an interspace being formed between the inner conduit's outer surface and the outer conduit's inner surface. The interspace between the inner conduit's outer surface and the outer conduit's inner surface contains an interspace liquid. The inner conduit is configured for guiding light coupled into the inner conduit, and dependent on the light's angle of incidence, total reflection occurs at a boundary between the inner conduit's outer surface and the interspace between the inner conduit and the outer conduit.
