HIGHLIGHTS
- who: September and collaborators from the Chulalongkorn University, Thailand have published the paper: A spatially non-overlapping dual-wavelength 2D FBG for the measurement of temperature and strain, in the Journal: (JOURNAL)
- what: This work proposed a 2D FBG based on the 2D spatial mask to design a dual-wavelength grating that could be easily engraved with a compact structure, thus measuring the temperature and strain. In the experiment, the OSA with resolution 10 p.m. is employed, so the resolution of temperature and strain can reach 0.93u00b0C and 10.8 u03bcu03b5, respectively.
