Classification: CPC G  H | IPC G  H

Claim 0:
1. 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.
