为解决光纤温度与应变传感器 (FTSS)灵敏度不足的问题，研究人员创新性地将反射式Lyot滤波器 (RLF)与法布里-珀罗干涉仪 (FPI)微腔结合，构建了改进级联 (M-cascading)结构的光纤游标传感器。实验表明，该传感器在温度、轴向应变和扭转测试中分别实现22.23 nm/°C、-25.29 pm/με和-85.8 pm/°的高灵敏度，放大 ...

NARVAL, a stellar spectropolarimeter, has recently been installed on the 2 meter diameter Bernard Lyot Telescope (INSU-CNRS) at the summit of the Pic du Midi in the French Pyrenees. Like its twin ...

The dune was spotted on Mars’ Lyot Crater region and researchers suspect it might be made of “finer material” than neighbouring dunes, according to a statement from the space agency.
