Abstract
A method for performing distributed pressure sensing including the steps of, forming a grating in a birefringent fiber, measuring the birefringence distribution along the length of the birefringent fiber, and determining pressure present along the length of the fiber using the measured the birefringence distribution. The invention also relates to a corresponding sensing device.
