我们目前的结果，从第一光纤相关光谱气体传感器，它不使用透镜以外的测量气室。该传感器测量乙炔（C2 H2）气体浓度。在大气压下用乙炔填充1米长的光子带隙光纤（PBGF），然后将其熔接到标准的实芯单模SMF-28光纤上，形成一个紧凑的、可卷绕的参考单元，而不需要任何透镜或体光学器件。由于细胞含有一定体积的气体
We present results from the first optical fibre correlation spectroscopy gas sensor which uses no lenses other than in the measurement gas cell. The sensor measures acetylene (C2H2) gas concentration. A 1-m length of photonic bandgap fibre (PBGF) was filled with acetylene at atmospheric pressure, then fusion spliced to standard, solid-core, single-mode SMF-28 fibre to form a compact, coilable, reference cell without the need for any lenses or bulk optics. As the cell contained a gas volume
