Abstract
The development of a new fiber Bragg grating (FBG) multiplexing technique is reported. The technique is based on a special 2D spectrometer and is potentially capable of interrogate near 2000 FBGs at high speed and in a random fashion, i.e. each FBG in the sensor array can be addressed at different sample rates ranging from 0 to several tens of kilohertz. The operating principle of the technique is presented with its potential performance indicators analyzed by theoretical calculation and computer simulation. Preliminary experimental result using an off-the-shelf spectrometer are also included in the paper.
