Abstract
An apparatus, and related method, relates generally to a fiber-optic sensing system. In such a system, fiber-optic sensors are in a rosette or rosette-like pattern. An optical circulator is coupled to receive a light signal from a broadband light source, to provide the light signal to the fiber-optic sensors, and to receive a returned optical signal from the fiber-optic sensors. A spectral engine is coupled to the optical circulator to receive the returned optical signal and configured to provide an output signal.

A fiber-optic sensing system, comprising:
- fiber-optic sensors of corresponding optical fibers in a rosette or rosette-like pattern;
- a broadband light source of a Fiber Bragg Grating analyzer for having Fiber Bragg Grating wavelengths in the rosette or rosette-like pattern in parallel;
- an optical circulator of the Fiber Bragg Grating analyzer coupled to receive a light signal from the broadband light source, to provide the light signal to the fiber-optic sensors, and to receive a returned optical signal from the fiber-optic sensors;
- and
- a spectral engine of the Fiber Bragg Grating analyzer coupled to the optical circulator to receive the returned optical signal and configured to provide an output signal.
