摘要：

The effect of external energy source on waveguide's transmitted blackbody radiation is examined. It is shown that the radiometric signal is increased because of external heat sources. This effect can be avoided by a proper external protecting layer. The transmitted laser energy is another cause of heating the waveguide's walls. To analyze these effects, the wall temperature was recorded by thermocouples and thermal camera. It is shown that the most-affected regions in the waveguide are the curved regions and the distal end. Gas cooling and external metal layers reduce this undesired heating of the walls.
