抄録

In order to measure accurately the flame temperature by means of the optical fiber thermometer, the fundamental sensor characteristics were made clear in the following points by using two kinds of calibration apparatus with the blackbody furnace and the semiconductor laser light source. The view angles of the flat-edge type sensor and the beveled-edge type sensor were very narrow within ±10° in pitch angle while the yaw angle characteristic of the beveled one was within ±15°. The decrement of radiation intensity due to the sapphire rod sensor and the optical fiber cable, which dominates the measurement accuracy of the flame temperature, was also calibrated quantitatively by using the blackbody furnace, and it was so large as 58% in the present beveled-edge sensor.
