|
摘要
为了实现非接触式高温测量,本文基于多光谱辐射测温理论,采用多路光电探测器,设计了多光谱快响应测温系统。对测量装置的测量原理、系统结构、系统标定等进行了阐述和分析。接着利用标准钨灯对装置进行了光谱响应系数标定,并通过标准辐射源进行了温度测量的实验验证,验证了测量装置用于高温测量的准确性。
In order to achieve non-contact high temperature measurement,multi-spectral fast-response temperature measuring system adopting multichannel photoelectric detectors is designed based on multispectral radiation temperature measured theory. The measuring principle,the system structure and calibration of the measuring system is elucidated and analyzed. The spectral response coefficient is standardized by the tungsten lamp.Experiments are carried out by measuring the temperature of the standard radiation source,demonstrating that this device is reliable in high temperature measurement.
