摘要
分析了光导纤维的传光原理及光耦合器的使用及耦合效率,主要介绍了在红点区域的红外测温技术中所使用的光纤传感器的作用。在其恶劣的测量环境下,经合理的光耦合,使红点区域(小目标)的信号能够得到精确的接收与测量。
This article analyzes the transmitting light principle of optical fiber and the application of photo-coupler and coupling efficiency and introduces mainly the function of using fiber-optical sensor of infrared radiation thermometer in the area of red dots. Under the bad measurement circumstances, after the reasonable optical coupling, the signals in the area of red dots (tiny target) can be received and measured accurately.
