Abstract :
A spiral fibre microbend-loss sensor having definite sensing characteristics is presented. By means of single-mode-fibre embedded metal springs, strain and deformation can be measured with good linearity and reproducibility and with a large dynamic range. The effects of spring parameters (radius, pitch, length) on the sensing performances are analysed and verified experimentally. Numerical simulations for the optimum design are performed
