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.

Method and device for pressure sensing

A Brillouin optoelectronic measurement method includes the steps of, providing a pump signal in a first end of an optical fiber to generate Brillouin backscattering, using the generated Brillouin backscattering to perform a measurement, wherein the pump signal includes a front pulse and a rear pulse, wherein the front pulse is modulated.
