Abstract
A fluorometer is provided for monitoring the quality of water, featuring an array of excitation sources, an array of multiple emission detectors and a signal processor. In the array of excitation sources, each excitation source provides respective excitation source optical signaling at a respective illuminating wavelength. The array of multiple emission detectors detects multiple emission wavelengths emitted from water containing information about multiple coexisting fluorescent species present in the water that emit optical radiation at at least two different wavelengths when illuminated by the respective illuminating wavelength provided from the array of excitation sources, and provide multiple emission detector signaling containing information about the multiple coexisting fluorescent species. The signal processor receives the multiple emission detector signaling, and determines corresponding signaling containing information about an identification of the multiple coexisting fluorescent species present in the water using a near-simultaneous identification technique, based upon the multiple emission detector signaling received.
