    Abstract: A spectroscopic detector suitable for detecting oil spills in an aquatic environment includes a buoyant container having an optical window; an optical energy generator mounted in the container for directing an optical energy beam through the window; an optical detector for generating an output signal in response to detecting a second optical energy beam received in the container through the window; and a beam splitter for directing the second optical energy beam to the optical detector. The generation of the optical energy beam and operation of the optical detector may be time gated to reduce thermal noise and isolate the sampled optical energy from background light. The optical energy beam preferably has UV components which inhibits the formation of biological organisms on the optical window.

    Abstract: A sensor for the reliable detection of oil spills using fluorescence techniques. An ultraviolet (UV) light source is located around an optical column with which selected wavelengths of fluorescing hydrocarbons or other substances can be detected. The source of UV light is held at a constant level and special techniques are employed to remove background optical noise from the various detected wavelength signals. Short and long term running averages are generated to detect oil spills. A special buoy is employed to allow the sensor to be oriented at a cavity in the buoy to reliable detect oil spills on waterways. The buoy has windows to enable surface water to freely pass through into the cavity while preventing turbulence from open water waves and wind. The buoy has a low center of gravity well below the water line with a large submerged segment to reduce heaving motions and provide a stable platform for the detection of fluorescing substances.

    Abstract: A method and apparatus for characterising individual particles in an aquatic mass (24) is disclosed. According to a first aspect of the invention, an interference pattern (22) is generated in the aquatic mass (24) by overlapping two beams (10, 12) of electromagnetic radiation. The region of overlap defines a probe volume (14) such that the interference pattern (22) is generated in the probe volume (14). A single particle (26) in the probe volume is illuminated with the interference pattern (22), causing said single particle (26) to emit radiation. The radiation emitted by the single particle (26) is detected, and spectral data derived from the detected radiation is used to determine a property of the single particle. The emitted radiation may be fluorescence. According to a further aspect of the invention, a similar arrangement is used to illuminate a single particle so that the particle scatters radiation via Raman scattering. The Raman-scattered radiation is detected and used to determine a property of the single particle (26).

The source (102) of UV light is held at a constant level and special techniques are employed to remove background optical noise from the various detected wavelength signals.

A special buoy (32) is employed to allow the sensor (30) to be oriented at a cavity in the buoy (32) to reliably detect oil spills on water-ways. The buoy (32) has windows (70) to enable surface water to freely pass through into the cavity (48) while preventing turbulence from open water waves and wind. The buoy (32) has a low center of gravity well below the water line with a large submerged segment to reduce heaving motions and provide a stable platform for the detection of fluorescing substances.
