    Abstract: 接着構造体(10)は、積層板(12A)、積層板(12B)、積層板(12A)と積層板(12B)とを接着する接着剤(14)、及び積層板(12A)と積層板(12B)とに挟まれる光ファイバ(16)を備える。光ファイバ(16)に所定の方向からのみ圧力が加えられると、光ファイバ(16)の断面形状が楕円形に変化するので、光スペクトルは複数(例えば2つ)のピークを持つ形状に変化する複屈折が生じる。光ファイバ(16)は、この複屈折によって積層板(12A)と積層板(12B)の接着状態を検出するためのセンサとして用いられる。これにより、接着構造体10は、部材同士が適切に接着されているか否かを判断できる。

    Abstract: An apparatus (200), comprising at least one fluorescence optical nanofiber (204) and at least one probe fiber (260), wherein a portion of the probe fiber (260) is disposed within a distance of one hundred nanofiber diameters from the optical nanofiber (204). The first and the second nanofiber ends (208,212) are disposed within a pressure-tight chamber (228), and a portion of the optical nanofiber (204) and the portion of the probe fiber (260) are each disposed outside the chamber (228). An electromagnetic energy source (SC) is arranged to direct source electromagnetic energy having a selected fluorescence frequency to a first nanofiber end (208), and a receiver (RCVR) is arranged to receive fluorescence energy via the probe fiber (260). Sampled downhole fluid (240) is disposed proximate to the nanofiber (204) and the probe fiber (260) portions, such that the sampled downhole fluid (240) provides the fluorescence energy in response to evanescant energy arising from the source electromagnetic energy present in the optical nanofiber (204).
    Additional systems and methods are disclosed.

    Abstract: A two-core optical fiber is provided for use in Brillouin distributed fiber sensor applications and systems. The two-core fiber includes a first and second core. Each core is configured to exhibit a Brillouin frequency shift greater than 30 Mhz relative to the other core. Further, each core possesses temperature and strain coefficients that differ from the other core. The cores can be configured to produce Brillouin frequency shift levels of at least 30 Mhz relative to one another. These differences in shift levels may be effected by adjustment of the material compositions, doping concentrations and/or refractive index profiles of each of the cores. These optical fibers may also be used in BOTDR- and BOTDA-based sensor systems and arrangements.
