摘要

在这项工作中，我们提出了一种基于少量钯涂层的Bragg光栅传感器。我们详细解释了制作过程，从纤维的蚀刻到钯的沉积。在该传感器中，Pd吸收的氢量与氢浓度有关，并引起改变FBG透射或反射光谱的应力。

Study of a palladium coated Bragg grating sensor to detect and measure low hydrogen concentrations

In this work we present a sensor based in a Bragg grating coated by a small amount of palladium. We explain the process of fabrication in detail, from the etching of the fiber to the deposition of the palladium. In this sensor the amount of hydrogen absorbed by the Pd is hydrogen concentration dependant and causes a stress that alters the transmission or reflection spectra of the FBG.
