摘要: 分析了光纤端面倾斜对光能量耦合的影响和光纤接收角的变化。结果表明，光纤端面倾斜对光能量的耦合具有较大的影响，同时使光纤的接收角也产生较大的偏移。把这些结果与标定的具体情况相结合，提出了在高温计标定中应采取的措施，以提高系统的测量精度。Abstract: The influence of inclination of the fiber end surface to coupling energy of a pyrometer and variation of the accepting angle of the fiber caused by the inclination is calculated. Results show that the inclination of the fiber end surface influences the coupling energy very much. At the same time, the inclination of the fiber end surface makes the accepting angle of the fiber a great deal. Connecting these results with the actual experiment and calibration situation, the influence of inclination of the fiber end surface to calibration is discussed and a more effective calibration technique is proposed.
