摘　　要：介绍了基于黑体辐射式测温原理的光纤高温计.比色测温能够最大程度地降低金属辐射率对测温精度的影响,使得测量结果更加接近物体真实温度.基于比色法的涡轮叶片辐射式光纤高温计能够提高燃气轮机内部温度测量的精度和测温准确性.This paper introduces the optical pyrometer which is based on the Planck＇s thermal Radiation Law. Colorimetry method makes the measuring results more closer to the metal＇ s real temperature. Optical pyrometers for turbine blades temperature measurement which is based on the colorimetric temperature measurement can improve the precision of gas turbine blades temperature measurement. Designing of pyrometer head is one of the most important parts during the optical pyrometry construction.
