[EN] We propose and demonstrate a sensing system with fiber Bragg grating sensors designed as discrete prolate spheroidal sequences (DPSS). In this way, we can encode all of the sensing devices in the network making sure ...

In this letter, a spectral encoding of fiber Bragg grating (FBG) sensors is proposed in order to solve their wavelength under overlapping conditions. Our technique uses optical orthogonal codes (OOCs) to define the spectral ...
