A fiber optic sensor system permits multiple parameters to be sensed using a single sensor. In a described embodiment, a method of sensing multiple parameters is provided in which an interferometric fiber optic sensor is connected to a variable wavelength light source. Light is transmitted from the light source through the sensor, with the light being swept over a range of wavelengths to measure relatively low frequency signals, and the light being maintained at a constant wavelength to measure relatively high frequency signals.

A sensor assembly having an optical fiber, a lens in optical communication with the optical fiber, a reflective surface spaced from the lens, for reflecting light from the beam back to the lens, a partially reflective surface positioned between the reflective surface and the lens, the partially reflective surface for reflecting light from the beam back to the lens, and an alignment device for aligning the lens and reflective surface with respect to one another, such that light from the beam of light transmitted from the lens reflects from the reflective surface back to the lens. The alignment device can have a rotational component and a base component, where the rotational component rotates to align a beam of light transmitted from the lens. The rotational component can also cooperate with the base component to move axially with respect to the reflective surfaces to align the beam for optimum power.

A system includes an optical source. The system further includes a reflective sensor remotely deployed from the optical source. The system further includes an optical processor. The system further includes a forward optical waveguide spanning the distance from, and transmitting light from, the optical source to the reflective sensor. The system further includes a return optical waveguide spanning the distance from, and transmitting light from, the reflective sensor to the optical processor. The forward optical waveguide follows substantially the same path as, but is completely separate from, the return optical waveguide.

A system is disclosed for measuring strain using a technique of detecting the optical path difference in a sensing interferometer using an interrogating interferometer including a chirped fiber Bragg grating in which the optical path difference in the sensing interferometer is changed with the strain in the sensing arm, whereas the optical path difference of the interrogating interferometer is changed only by changing the center wavelength of addressing light, making use of the wavelength-dependency on the penetration depth inside the chirped fiber Bragg grating interferometer. Consequently, strain in the sensing interferometer can be assessed by determining the wavelength in which a coherence matched condition between the sensing and interrogation interferometers is attained.
