Abstract
We are developing a submersible deep ultraviolet laser induced native fluorescence (UVLINF) instrument to detect and identify trace levels of chemicals of life and other organic chemicals in water column of lakes and ocean. The instrument can also measure and log temperature, pressure and conductivity of the ambient water environment. The instrument is solar-blind and can operate up to depths of few hundred meters. The proposed concept uses a 224.3nm laser to excite and measure fluorescence in multiple UV and visible wavebands as a function of depth in a body of water. These fluorescence measurements can then be interpreted to classify organic material discovered during submersion of the instrument. The fluorescence instrument has the advantage that very sensitive measurements can be made in microseconds so that vertical profiling of a body of water can be done rapidly. The instrument also can be used for fast analysis of water quality from different sources.
