Simultaneous Measurement of Thermal Gradient and Average Temperature in Concrete Blocks Using Nonuniform Long-Period Optical Fiber Gratings
Abstract
A recent increase in structural integrity requirements has led to a higher demand for accurate heat flux and temperature readings of building materiàl substrates. In this work, simultaneous two-parameter measurements of the average temperature and the temperature difference in concrete blocks are reported. To this end, long-period gratings (LPGs) were commissioned in a boron-doped photosensitive optical fiber using a pulsed CO2 laser. The …
