摘要:

在近红外比色测温中,当炉内环境辐射强度高于被测工件辐射强度时,环境辐射对测量结果的准确性有显著影响。为了得到较为理想的测量结果,通过对被测工件在不同温度场下的投射辐射吸收率、反射率和透射率的分析,得出了几者之间的关系,为准确测量工件的实际温度提供了依据;在此基础上,提出一种新的解决高温背景辐射影响的方法。

Abstract:

In temperature measurement with near-infrared colorimetry method, if the environment radiation intensity in furnace is higher than that of work piece being detected, the measurement result will be influenced by environment radiation significantly。In order to obtain more satisfied measurements result relatively ,according to measurement analysis,we found out the relationship between projected absorption rate of radiation, reflectivity and transmittance of the work piece detected in different temperature field,which supplies theory basis for measuring the real temperature of work piece accurately,furthermore,on the basis of which,a novel resolution to solve background radiation in high temperature is proposed。

Key words: optoelectronics, colorimetry of temperature measurement, environment temperature, influence ratio, radiation
