Laser-induced fluorescence and Raman scattering for real time measurement of suspended particulate matter
Abstract
Induced inelastic scattering such as Raman and fluorescence of artificially generated aerosols has been observed for excitation with either continuous or pulsed lasers. Results indicate that fluorescence arising from most aerosols can degrade the signal-to-noise ratio to unpractical values when measuring Raman signals. The analytical feasibility of the technique for the real time monitoring of suspended particles is also discussed.
