| Title: | CO₂ laser-grooved long period fiber grating temperature sensor system based on intensity modulation | Authors: | Wang, Y Wang, D Jin, W |
Issue Date: | 1-Nov-2006 | Source: | Applied optics, 1 Nov. 2006, v. 45, no. 31, p. 7966-7970 | Abstract: | A long period fiber grating (LPFG) temperature sensor system based on intensity modulation is developed. The LPFG employed is fabricated by the use of a focused CO₂ laser beam to carve periodic grooves on the fiber. The temperature measurement resolution of up to 0.1°C has been obtained within the temperature range between 20°C and 100°C. The system uses a simple intensity measurement method and exhibits the advantages of convenient intensity measurement, double temperature sensitivity, high resolution, simple configuration, and low cost. | Keywords: | Cost effectiveness Diffraction gratings Optical fibers Sensors Temperature distribution Temperature measurement |
