Abstract: A swept frequency fluorometer having a signal processor or processing module configured to:
receive signaling containing information about reflected light off one or more fluorescence species-of-interest in a liquid sample that is swept with light having a variable frequency range, the information including a characteristic optical frequency corresponding to a fluorescence species-of-interest in the liquid, and a characteristic/lifetime optical frequency corresponding to a distinct fluorescence lifetime in which the fluorescence species-of-interest remains in an excited state; and
provide corresponding signaling containing information about an identity of the fluorescence species-of-interest detected and distinguished from overlapping fluorescence species in the liquid using the characteristic/lifetime optical frequency, based upon the signaling received.

Abstract: A turbidity sensor featuring a signal processor or processing module configured to: receive signaling containing information about light reflected off suspended matter in a liquid and sensed by a linear sensor array having rows and columns of optical elements; and determine corresponding signaling containing information about a concentration of turbidity of the liquid, based upon the signaling received.

Abstract: A spatial gradient-based fluorometer featuring a signal processor or processing module configured to: receive signaling containing information about light reflected off fluorophores in a liquid and sensed by a linear sensor array having a length and rows and columns of optical elements; and determine corresponding signaling containing information about a fluorophore concentration of the liquid a fluorophore concentration of the liquid that depends on a spatial gradient of the light reflected and sensed along the length of the linear sensor array, based upon the signaling received.
