WebWe present a distributed fiber optic sensing scheme to study 3D temperature fields inside concrete containers submitted to fire. High spatial resolution (3cm to 13cm), temperature uncertainty better than 3°C and rapid measurements (in the minute range) were required. We thus compared advantages and drawbacks of three sensing chains, based on Rayleigh, … WebDesigned for use in an epi-illumination geometry Raman microscope, the laser reflector is an image quality AR-coated glass element with a centered 2mm diameter aluminum mirror. Mounted at 45°, it reflects the laser into the objective, and then transmits all but a small fraction of the Rayleigh and Raman scattered light collected with the ...
