A multi wavelength optical sensing technique has been tested for monitoring a smoke or aerosol polydispersion so as to allow positive discrimination between types of aerosols or particles. It uses a polychromatic LED and spectral analysis in real-time via the technique of chromatic modulation which allows a three-parameter description to characterise spectral interactions due to scattering.
