Abstract

In the aviation field, the instrument must be small, light, and vibration resistant. A Fiber Bragg Grating (FBG) sensor interrogator with a linear variable filter (LVF) can be well suited for the requirements in the aviation field, due to its special optical structure. Moreover, it has a great prospect of applications in the aviation field. An error model is established and the simulation results show that the inhomogeneous illumination of the incident light has an impact on the sensitivity of the interrogator. This paper defines the degree of inhomogeneity to describe the effect of inhomogeneous illumination. Using this model, the design of the interrogator can be optimized to improve its sensitivity.
