Classification of soil texture and content by near-infrared spectroscopy

This description relates to a predictive model for estimating the proportions of sand, silt, and clay in a soil sample based on near-infrared spectroscopy (NIRS) performed on the soil samples. The soil texture prediction model is trained using benchmark NIRS test data and collected spectra of soil samples for which the benchmark test data has been collected. The estimates produced by the model can be used to determinate a variety of properties of the soil sample, such as hydrological properties and soil quality. Knowledge of these properties are useful for informing decisions that agronomists, producers, or farm managers make throughout the year. For example, agronomists use the determined properties to infer how the soil will perform under any given treatment or application, for example applying seeds, fertilizer, pesticide, and herbicide.

INTEGRATED FILTER REMOTE GAS CORRELATION SENSOR

Abstract An integrated optical sensor enables the detection and identification of one or more remote gases using a transmission filter that matches specific absorption features of a remote gas and is detected using a single photodetection element. The sensor comprises an integrated optical component that is characterized by its transmission spectrum which corresponds to absorption or emission features of a target gas over a defined spectral bandpass, and the ability to have a reversibly tunable transmission spectrum. The change in the optical power output from the sensor as the transmission spectrum is tuned is proportional to the optical depth of the target gas absorption lines when viewed with a background light source. The optical power output from the integrated optical component is therefore related to the absorption spectrum of the input light Physical properties of the sensor are tailored to produce a quasi-periodic transmission spectrum that results in a stronger signal contrast ...

Increased Absorption-Measurement Accuracy Through Windowing of Photon-Transit Times to Account for Scattering in Continuous Webs and Powders

Radiation scattering is one of the main contributors to the uncertainty of near infrared (NIR) measurements. Enhanced absorption-measurement accuracy for NIR sensors is achieved by using a combination of NIR spectroscopy and time-of-flight techniques to select photons that are the result of a given mean free path within a moving sample target. By measuring absorption as a function of path length or by windowing signals that are attributable to excessive scattering of NIR radiation within the sample, this technique affords the calculation of more accurate and more universal calibrations. The NIR sensor employs short or ultra-short laser pulses to create NIR that is directed to the moving sample and emerging radiation is detected over time. Windowing effectively truncates non-contributing measurements.

Method And Technique For Verification Of Olive Oil Composition

A new rapid Fourier transform near infrared (FT-NIR) spectroscopic method is described to screen for the authenticity of extra virgin olive oils (EVOO) and to determine the kind and amount of an adulterant in EVOO. To screen EVOO, a partial least squares (PLS1) calibration model was developed to estimate a newly created FT-NIR Index based on the carbonyl overtone absorptions in the FT-NIR spectra of EVOO and other mixtures attributed to volatile (5200 cm) and non-volatile (5180 cm″1) components. Spectra were also used to predict the fatty acid (FA) composition of EVOO or samples spiked with an adulterant using previously developed PLS1 calibration models and modified for this purpose. To identify the type and determine the quantity of an adulterant, gravimetric mixtures were prepared by spiking an EVOO with different concentrations of each adulterant. Based on FT-NIR spectra, four PLS1 calibration models were developed for four specific groups of adulterants each with a characteristic FA composition. These different PLS1 calibration models were used for prediction of type and amount of adulterant. A more comprehensive double or triple adulterant PLS1 calibration models were also developed and tested which provided means of analyzing commercial virgin olive oils which had been adulterated. 1.
