Abstract
A leak detector () includes a sensor head (), a light source () optically coupled to the sensor head and operable to generate excitation light. A detector () is optically coupled to the sensor head and operable to detect fluorescence light. A signal processing unit () is coupled to the detector and operable to signal a leak condition responsive to an intensity of the fluorescence light exceeding a threshold. A fluid-tight enclosure () encloses at least the light source, the detector, and the signal processing unit.
