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.
Claims16
A turbidity sensor comprising:
- a quasi-collimated light source having a length and being configured to provide quasi-collimated light to a liquid sample that causes gradient light to scatter and reflect transversely off suspended matter in the liquid sample along the length of the collimated light source;
- a linear sensor array having rows and columns of optical elements and configured to sense the gradient light scattered and reflected transversely off the suspended matter in the liquid sample along the length of the collimated light source and provide signaling containing information about the gradient light sensed;
- and
- a signal processor or processing module configured to:
- receive the signaling;
- and
- determine corresponding signaling containing information about a concentration of turbidity of the liquid sample that spatially depends on an attenuation of the gradient light sensed across the linear sensor array and along the length of the collimated light source, based upon the signaling received.

A method for determining a concentration of turbidity, comprising:
- providing quasi-collimated light to a liquid sample with a quasi-collimated light source having a length that causes gradient light to scatter and reflect transversely off suspended matter in the liquid sample along the length of the collimated light source;
- sensing the gradient light scattered and reflected transversely off the suspended matter in the liquid sample along the length of the collimated light source with a linear sensor array having rows and columns of optical elements;
- providing signaling containing information about the gradient light sensed;
- receiving, with a signal processor or processing module, the signaling;
- and
- determining, with the signal processor or processing module, corresponding signaling containing information about a concentration of a parameter of the liquid sample that spatially depends on an attenuation of the gradient light sensed across the linear sensor array and along the length of the collimated light source, based upon the signaling received.
