Simultaneous strain and temperature measurement based on a photonic crystal fiber modal-interference interacting with a long period fiber grating. Optics Communications, 285(24), 4874-4877. | Series/Report no.: | Optics communications | Abstract: | An alternative all-fiber sensor for simultaneous strain and temperature measurement based on a photonic crystal fiber (PCF) spliced between single-mode fibers cascaded with a long period grating (LPG) is proposed. By collapsing the air holes at two splicing regions along the PCF, a simple but effective modal-interference (MI) is occurred between the core and cladding modes of the PCF. Due to the different responses on the changes of strain and temperature on the MI and the cascaded LPG, the strain and temperature can be measured simultaneously. Experimental results show that the sensing resolution of 9.1 με in strain measurement is experimentally achieved over a range of 2640 με, while the temperature sensing resolution is 0.27 °C within a range of 30–100 °C. | URI: | https://hdl.handle.net/10356/97242 http://hdl.handle.net/10220/10597 |
