Claim 8:
9. 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.
