The outputs of this kind of optical fiber reflective sensor are independent of the characteristics of the light source, of the losses in the ambient medium and the target reflectivity.

这种可补偿型光纤位移传感器的输出与传感器光源的特性、环境介质以及被测目标表面的性质无关。

When nearly 30 years ago Dr. Jacob Fraden invented an ear thermometer working on this second principle, the infrared light sensor was so large that he needed a narrow gold-plated reflective tube to channel the light from the ear drum to the sensor.
