Abstract :
A novel interrogation method for fibre optic loss sensors based on the analysis of transmitted and reflected powers of a continuous wave light source is presented. The position of the loss region is determined from unique dependencies between normalised powers for different locations of the disturbance along the fibre containing a number of Bragg gratings
