Abstract :
A novel method for measuring axial residual stress in optical fibre is presented. It is shown that axial residual stress profiles can be reconstructed from optical retardation data measured for several orientations of a fibre. Using this method, the axial stress profile in polarisation-maintaining fibre has been clarified.
