A novel system capable of simultaneously interrogating several fiber Bragg grating (FBG) sensors is described. The system utilizes an arrangement of linear and chirped structures, photodiodes, and an asymmetric ramped-grating profile. The interrogation of one sensor involves two gratings, where a linear FBG acts as the sensor and a ramped-grating profile modulates its reflection intensity.
