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 method and a device for fatigue testing of photochromic, fluorescent or phosphorescent dye/dyes or of a mixture of at least two of them, in which a sample (3) containing photochromic, fluorescent or phosphorescent dye/dyes or a mixture of at least two of them is exposed to a predetermined number of cycles of luminous exposure to an excitation light beam (81), which evokes a color response of the photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them in the sample (3). Before and/or during and/or after each predetermined exposure to the excitation light beam (81), the sample (3) containing the photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them is exposed at least once to irradiation by an exposure light beam (71), due to which the dye/dyes is/are subject to fatigue loading. Simultaneously, a measuring light beam (41) is introduced to the sample (3) and is reflected from it, whereby the change and/or the course of the change in the characteristics of the measuring light beam (41) reflected from the sample is monitored by a spectrometer (94). From this change and/or the course of the change it is possible to deduce the course of the color response and/or the change in the color response of the particular photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them in the sample (3) to the exposure to an excitation light beam (81) and thus it is possible to deduce the fatigue of this photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them.

Abstract: A test strip with an incorporated optical waveguide and deflectors punched through the optical waveguide allows light to exit through a layer of the test strip and be detected by a photo detector. Using light and a photodetector, these uniquely coded strips are identified. The waveguide can be constructed by sandwiching two layers of the test strip around a light transmissible layer. This configuration allows light to be transmitted through the test strip and out the other end, as well as allowing some light to escape the deflector. This light is detected by a photodetector mounted in the analyte test meter. The deflectors may be placed in patterns such that detection of this light indicates certain characteristics of the strip, such as non-counterfeit, regional identification, type of analyte tested, and coding information.
