中文摘要	a novel fiber bragg grating (fbg) pressure sensor based on the double shell cylinder with temperature compensation is presented. in the sensing scheme, a sensing fbg is affixed in the tangential direction on the outer surface of the inner cylinder, and another fbg is affixed in the axial direction to compensate the temperature fluctuation. based on the theory of elasticity, the theoretical analysis of the strain distribution of the sensing shell is presented. experiments are carried out to test the performance of the sensor. a pressure sensitivity of 0.0937 nm/mpa has been achieved. the experimental results also demonstrate that the two fbgs have the same temperature sensitivity, which can be utilized to compensate the temperature induced wavelength shift during the pressure measurement.
