光栅棱镜内调制比色测温仪研究

Study on Intramodulated Colorimetric Temperature Measurement Device with Grating Prism

探讨了在内调制光电管的基础上使用光栅棱镜作为前端分色设备进行比色测温的方法 ,结果表明 :与使用光纤分束作为前端分色设备的方法相比 ,其设备简单 ,并具有工作波长及其带宽选择灵活的优点 。

A method using grating prism as a front end color scanner to measure temperature on the basis of intramodulated photodetector is discussed.The result shows that it is simpler and more flexible compared with the method using bifurcated fiber as the front end color scanner which can meet the requirements of practical use.
