Airborne monitoring of surface water pollutants by fluorescence spectroscopy
Abstract
An airborne laserfluorosensor has been used to record fluorescence profiles of a controlled oil spill and of the river effluent from a pulp and paper mill. A pulsed ultraviolet laser is used as the excitation source in conjunction with a telescope receiver and photomultiplier detector. The complete system, including power supplies and monitoring and recording equipment, was installed and flown on a DC-3 aircraft. The fluorescence profiles exhibited excellent signal-to-noise ratios and ground resolution, thereby providing for good discrimination between targets of different fluorescence quantum efficiency. By making a number of passes over a particular target area, it has been shown that the measured fluorescence profiles demonstrate target changes both in space and time. Information gained from these remote sensing measurements has provided data for use in the design of an advanced laserfluorosensor capable of recording fluorescence spectra and decay time data in addition to fluorescence profiles similar to those presented here.
