    Abstract: A fiber-optic sensor can have a Michelson sensor portion and a Mach-Zehnder sensor portion. A first splitter-coupler can be configured to split incoming light between a first fiber portion and a second fiber portion. A first polarization-phase conjugation device can be configured to conjugate a polarization phase of incident light corresponding to the first fiber portion, and a second polarization-phase conjugation device can be configured to conjugate a polarization phase of incident light corresponding to the second fiber portion. Each of the first and second polarization-phase conjugation devices can be configured to reflect light toward a detector and through the respective first and second fiber portions. A coupler can be configured to join light in the first fiber portion with light in the second fiber portion, and a third fiber portion can be configured to receive light from the coupler and to illuminate a second detector.

    Abstract: A sensor element is disclosed. The sensor element comprises a first element which is nanoporous, and a second element which is nanoporous, the second element enclosing the first element. The surfaces of the nanopores of the first- and second element differ in hydrophilicity, so that the surfaces of the nanopores of one element is generally more hydrophobic while the other is generally more hydrophilic, and hence the sensor element is capable of selectively having the first element filled with a fluid. The sensor element is capable of guiding light through the fluid-filled first element and can act as a nanoporous waveguide. The sensor element according to the invention is particularly useful for spectroscopy on fluids.

    Abstract: The present disclosure describes the use and the manufacture of a fiber optic sensor having an angled terminal portion of a fiber optic element. In one embodiment, an optical fiber is cut at an angle and a portion of the fiber's jacket is removed near the angle so that the cladding is exposed. Light may then travel through the fiber, reflect off the angled portion, and emit through the exposed cladding into a patient. Light may also be collected from the patient using the same or a different fiber optic element having an angled terminal portion. In one embodiment, the emitted light can then be collected and analyzed to derive various physiological parameters. In certain embodiments, the fiber optic sensor may be used in environments where metallic and/or electronic sensors are not suitable.

    Abstract: Disclosed is a spectroscopic system having a fiber-optic probe for simultaneous IR and Raman measurement. The probe includes a single strand of optical fiber, such as sapphire which is suitable for IR absorption measurements as far as 4 μm and Raman excitation at wavelengths as short as 300 nm. The probe is immersed in the sample and functions in the evanescent wave mode for both IR absorption and Raman scattering measurements. The sensing system makes possible the synergistic, and simultaneous, analysis of both IR and Raman data in an integrated device.

    Abstract: The present invention relates to a method and system of array imaging that extends or maximizes the longevity of the sensor array by minimizing the effects of photobleaching. The imaging system has a light source, a variable exposure aperture, and a variable filter system. The system extends the longevity of sensors by (1) using the variable exposure aperture to selectively expose sections of the sensor array containing representative numbers of each type of sensor, and/or (2) using the variable filter system to control the intensity of the excitation light, providing only the intensity required to induce the appropriate excitation and increasing that intensity over time as necessary to counteract the effects of photobleaching.
