Abstract
A turbidity sensor for measuring a full range of particulate content in a turbid environment, including a method thereof. The turbidity sensor includes a laser light source for emitting laser light through the particulate content. The turbidity sensor additionally includes at least one light-sensitive detector located proximate to the laser light source for the detection of light scattered from particles of the particulate content that come into contact with laser light emitted from the laser light source, thereby permitting the accurate measurement of the turbidity of the turbid environment. A plurality of light-sensitive detectors may be employed, including a back scatter detector, a side scatter detector, a forward scatter detector, and a direct transmission detector. The light-sensitive detectors may be arranged in a geometric configuration of light-sensitive detectors with respect to the laser light source.
