| Abstract: | A method is proposed to minimize the effect of temperature on a long-period fiber grating (LPG), enabling its effective use for the interrogation of wavelength-modulated fiber Bragg grating (FBG) sensors. The temperature dependence of LPG is compensated by means of creating the opposite effect from the temperature-induced strain, attributed by appropriately encapsulating in a specially designed Teflon tube. The encapsulated LPG has achieved six times stabilization over the bare LPG response for the temperature range of 20°C to 50°C. Application of the athermalized LPG for interrogation of an FBG-based temperature sensor is experimentally demonstrated |
