Abstract: A system for detecting leaks from a subsea system is disclosed which includes at least one subsea structure anchored to a sea floor, a fluorescence detector attached to the subsea structure, the fluorescence detector adapted to generate a light beam having a wavelength that will fluoresce material leaking from the subsea system when the material is irradiated with the light beam, and a camera adapted to observe the fluorescence of the material as it is being irradiated by the light source.

Abstract: A fluorometer comprising an excitation system including an excitation source for producing excitation light capable of causing fluorescence in fluorescent material; and a detection system for detecting said fluorescence. The excitation source comprises one or more light emitting diodes (LEDs) associated with means for causing said excitation light to form a beam that projects, during use, from the fluorometer. In one embodiment, the excitation system and the detection system are located in respective separate housings, the angular disposition between the housings being adjustable. In other embodiments, the excitation system and the detection system are located in the same housing. The fluorometer is particularly suited for use in detecting leaks in aqueous environments, especially when mounted on an underwater vehicle.

Abstract: The present invention describes a novel optical technique for detecting and quantifying the binding of molecules to selective binding sites on synthetically formed molecular imprinted polymers using Raman Spectroscopy. Such a technique has immense application to the pharmaceutical and environmental industries.
