摘要：There is described a sensor apparatus. It comprises an interrogator comprisinga light source emitting pulses having a wavelength about an average wavelength; and a

fiber Bragg grating (FBG) arrangement. The arrangement comprises a FBG sensor arraycomprising a plurality of FBG sensors on an optical fiber and being for reflecting thepulses, thereby producing reflected pulses at each one of the FBG sensors. FBG sensorsof a given FBG sensor array have a spatial separation therebetween which is sufficient toallow, at a receiver, a temporal discrimination between the reflected pulses produced byeach one of the FBG sensors. The FBG sensor array has a spectral reflection window whichcomprises the average wavelength.
