    Abstract: An optical fiber environmental detection system comprising an interferometer, a broadband light source and a detector is disclosed. The interferometer further comprises a thin core fiber, a first single mode fiber and a second single mode fiber; wherein the thin core fiber is coupled to the first and second single mode fiber via a first junction and a second junction respectively. When an emission light reaches the first junction, high-order cladding modes will be excited. The excited cladding modes will interfere with the core mode at the second junction. The interferences determine the intensity maximum or minimum of the received signal. When there is an ambient environmental change, a shift of the received signal would be induced. According to the shift, environmental change, for instance ambient temperature, could be determined.

    Abstract: A cavity thermal detector assembly is presented that allows both tunable narrowband and broadband operation. This allows for high light efficiency, low thermal time constant, and flexibility in designing the optical path. The thermal detector/filter layers are part of the top mirror or mirrors of a Gires-Tournois-type optical cavity and provide absorption and reflection that can be adjusted to the desired width and position of the detected band. Tuning, if desired, can be achieved by applying micromechanical methods. Broadband operation may be achieved by bringing the sensor close to the bottom mirror. In this mode, the sensor or its supports may or may not touch over a small area.

    Abstract: The invention concerns a tandem interferometer for temperature sensing. The low coherence interferometry (LCI) system comprises a polarization-based sensing interferometer comprising a birefringent crystal having a sensor temperature sensitivity and a birefringence dispersion, and a readout interferometer being either a Fizeau interferometer using an optical wedge or a polarization interferometer using a birefringent wedge. In one embodiment of the invention, the birefringent crystal has dispersion properties similar to that of the birefringent wedge or that of the optical wedge of the readout interferometer. The present invention also provides a signal processing method for correcting the dispersion effect and for noise filtering in LCI-based optical sensors of the tandem interferometer arrangement.
