Ad. Kersey et al., MULTIPLEXED FIBER BRAGG GRATING STRAIN-SENSOR SYSTEM WITH A FIBER FABRY-PEROT WAVELENGTH FILTER, Optics letters, 18(16), 1993, pp. 1370-1372
The use of a fiber Fabry-Perot filter for detecting the wavelength shi
ft of a fiber Bragg grating sensor or network of sensor elements along
a common fiber path is described. Results obtained by using a system
with four sensor elements are presented.
