Technology Opportunities

Methods and systems used to perform sweep-free stimulated Brillouin scattering-based fiber optical sensing are described. In one aspect, a method includes interrogating different parts of a Brillouin gain spectrum using multiple optical tones in an optical fiber. The interrogating includes ...

TechnologyThis method is based on the Brillouin effect in optical fibers. By using a simple single mode optical fiber, strain is measured in a distributed manner along the entire fiber length, simultaneously, in high repetition rate. By attaching/planting the optical fiber to/in a mechanical ...
