Study of the Second Order Sensitivity of the Fiber Bragg Gratings
According to the Bragging equation, the general mathematical formulas of the temperature change error and the strain error are got under the consideration of the second-order temperature sensitivity and the second-order strain sensitivity. The two error curves are given in the conditions of T = 20°C and e = 1000me.
