Abstract: A system and method for in-field near infrared spectroscopy (NIRS) analysis of rubber and resin concentrations a guayule plant is provided. The system includes a wagon or other vehicle with the NIRS device mounted on the wagon. A computer or processor electrically coupled to the NIRS device is also housed within an area or extension of the wagon. During measurement of a guayule plant in the field, a guayule plant covering is placed over the guayule plant and a light shield coupled to the NIRS device is inserted into an opening on the guayule plant covering. The NIRS device is configured to perform a reading of the guayule plant within the plant covering and communicate results of the reading to the computer. A calibration equation is then preferably applied to the guayule plant readings to produce the rubber and resin concentrations of the guayule plant.

Abstract: A method for measuring a sample to identify a chemical includes receiving respective spectra for each of a plurality of chemicals. Using a processor, a plurality of binary mathematical filters are computed using the received spectra. A spatial light modulator is adjusted according to a selected mathematical filter. Light that has interacted with the sample is dispersed over the surface of the spatial light modulator, so that the spatial light modulator provides light at wavelengths corresponding to the selected mathematical filter. The light provided by the spatial light modulator is measured to provide a score corresponding to the selected mathematical filter. Filter scores are combined to determine a chemical amount. The processor can operate detection apparatus having a light source, an objective for focusing source light onto the sample, a spatial light modulator, and a detector for detecting the modulator output.
