Researchers repurpose 'damaged' polymer optical fibers to precisely measure magnetic fields
Optical fiber sensors can measure strain, temperature, pressure, and many other physical parameters along the fibers, but they are currently immune to electromagnetic noise -- interference from other external electric or magnetic interactions. It is a desirable trait, until the effect of the electromagnetic field on the fibers needs to be measured. An international research team has used what was previously considered a 'damaged' part of an optical fiber to develop such a magnetic field sensor. (2021-01-07)
