Optical Sensor for Analyzing a Stream of an Agricultural Product to Determine its Constituents (RFT-30)
An optical sensor for use in measuring constituents of an agricultural product. An optical sensing window passes a stream of the agricultural product, and a radiation source irradiates the stream as it passes through the optical sensing window. A receiver receives radiation transmitted through the stream and converts it into a corresponding electrical signal using a spectrometer. The electrical signal is digitized to produce a series of data points corresponding to particular wavelengths. A processor normalizes the data points using a reference value in order to generate processed data points that can be used to predict a constituent content of the agricultural product.
