Abstract: An apparatus for detecting sea mines is disclosed. The apparatus includes a pulsed laser, a collection optics, a long-pass beam splitter, a short-pass beam splitter, a Laser Imaging, Detection and Ranging (LIDAR) channel imager, a Raman channel imager and a florescence channel imager. After the pulsed laser has sent a laser pulse to an ocean surface, the collection optics collects Rayleigh, Raman and florescence scattering return signals reflected from the ocean surface as a result of the laser pulse laser striking the ocean surface and any objects therein. The long-band beam splitter directs the Rayleigh scattering return signals to the LIDAR channel imager. The short-band beam splitter directs the Raman return signals to the Raman channel imager, and directs the florescence return signals to the florescence channel imager.

Abstract: Cobalt-nickel oxide films of nominal 100 nm thickness, and resistivity as low as 0.06 ?·cm have been deposited by spin-casting from both aqueous and organic precursor solutions followed by annealing at 450° C. in air. An increase in film resistivity was found upon substitution of other cations (e.g., Zn2+, Al3+) for Ni in the spinel structure. However, some improvement in the mechanical properties of the films resulted. On the other hand, addition of small amounts of Li decreased the resistivity. A combination of XRD, XPS, UV/Vis and Raman spectroscopy indicated that NiCo2O4 is the primary conducting component and that the conductivity reaches a maximum at this stoichiometry. When x<0.67, NiO forms leading to an increase in resistivity; when x>0.67, the oxide was all spinel but the increased Co content lowered the conductivity.

Films deposited on sapphire substrates exhibit a refractive index of about 1.7 and are relatively transparent in the wavelength region from 0.6 to 10.0 &mgr;m. They are also magnetic. The electrical and spectroscopic properties of the oxides have been studied as a function of x=Co/(Co+Ni) ratio.

Abstract: Optrode apparatus for detecting constituents of a fluid medium includes an optical fiber (13, 13a to 13e) having a metal coating (22, 22a to 22e) on at least a portion of a light transmissive core (17, 17a to 17d). The metal is one, such as silver, gold or copper, which enhances emission of Raman signal frequencies by molecules adsorbed on the surface of the coating when monochromatic probe light of a different frequency is scattered by such molecules and the metal coating is sufficiently thin to transmit light between the absorbed molecules and the core of the fiber. Probe light is directed into one end of the fiber and a detector (16, 16d, 16e) analyzes light emitted from the fiber for Raman frequencies that identify one or more particular molecular species. In one form, the optrode (13e) may function as a working electrode of an electrochemical cell (53) while also serving to detect the products of oxidation or reduction reactions which occur at the electrode surface.
