This work proposes and demonstrates a biaxial sensing inclinometer based on two FBGs surfacemounted on two separate thin cantilevers with a diminishable cross-axis sensitivity. The measured sensitivities for the inclination angles in the x-z plane and y-z plane are 34.87 and 33.49 pm/deg, respective...
