Abstract
Disclosed is a real-time fluorescence imaging system for detecting on-site the presence and boundaries of spills of insulating liquids for transformers and capacitors and other fluorescing materials providing a two- dimensional image of the spill having excitement means positionable near a spill for exciting fluorescence emissions from the spill materials, image intensification means for intensifying the fluorescent emissions, first detection means positionable to detect intensified fluorescent emissions from the insulating liquids and generating a detection signal, and display means for receiving the detection signal and generating a real-time video image of the presence and boundaries of the spill. The present invention also includes pulse means for causing the excitement means to periodically excite fluorescent emissions from the insulating liquids and control means for controlling the intensification means to intensify only during periods of fluorescent excitation.
