Abstract: Methods for sorting haploid maize kernels in haploid induction crosses are provided. A method of sorting haploid kernels can include capturing near-infrared (NIR) spectra and applying a general multivariate statistical model to the acquired NIR spectra to discriminate haploid kernels from diploid-hybrid kernels mixed therein. NIR spectra can be collected on a single kernel using a high-throughput apparatus such that the amount of time required to analyze individual kernels can be significantly reduced in comparison to existing NIR technology and in comparison to traditional manual sorting.

Abstract: A system including a light source, sampling tray, and a plurality of fiber optics positioned to achieve high contrast to improve accuracy and eliminate the need to rotate the sample. A composite light image from the fiber optics is fed to a spectrometer which converts the reflected light into a fingerprint corresponding to the concentration of at least one substance in the sample. The fingerprint is processed by a statistical model to determine concentration level of the at least one substance in the sample and the concentration level is then displayed.

Abstract: A light source may illuminate a scene with amplitude-modulated light. The scene may include fluorescent material. The amplitude modulation may be periodic, and the frequency of the amplitude modulation may be swept. During the sweep, a time-of-flight sensor may take measurements of light returning from the scene. A computer may calculate, for each pixel in the sensor, a vector of complex numbers. Each complex number in the vector may encode phase and amplitude of light incident at the pixel and may correspond to measurements taken at a given frequency in the sweep. A computer may, based on phase of the complex numbers for a pixel, calculate fluorescence lifetime and scene depth of a scene point that corresponds to the pixel.

Abstract: The present invention provides a Voigt line shape fitting method, including step 1: Calculate a Gauss line shape function and a Lorentz line shape function, and calculate a Voigt line shape function. Step 2: For determined line shape parameters to be fitted, calculate partial derivatives of the Voigt line shape function with respect to the parameters, convert a partial derivative of the Voigt line shape function with respect to a parameter into a partial derivative of the Gauss line shape function or the Lorentz line shape function with respect to the parameter. Step 3: Substitute the Voigt line shape function and the partial derivative of the Voigt line shape function with respect to the parameter to be fitted, into a least squares algorithm step, perform least squares fitting calculation, and determine whether to terminate the least squares fitting calculation or return to step 1 to perform next iterative calculation.

Abstract: A method for estimating a value of a kerogen property in a subsurface formation where the value of the kerogen property is unknown. The method includes: measuring spectral intensity values over an infrared (IR) spectral range for a selected sample from the subsurface formation; determining a range of values representing the measured spectral intensity values corresponding to a vibrational mode attributable to kerogen in the selected sample, the range of values including values representing uncertainty in the measured spectral intensity over the portion of the spectral range; and inputting values from the range of values into a stochastic or simple regression model to determine an estimated value of the kerogen property in the selected sample.

Abstract: An imaging device includes laser diodes (LDs) generating near-infrared wavelength light, lenses configured to deliver the light to tissue, a first receiver having one or more detectors, and a first part with at least one of the LDs capable of being pulsed. The first receiver receives light reflected from the tissue and is synchronized to the pulsed light and configured to perform a time-of-flight measurement. An infrared camera receives light reflected by the tissue from a second part of the imaging device. The camera captures light while the second part is off, and while the second part is on to generate corresponding signals, and differences the signals to generate an image. An array of LDs generates a grid of spots on the tissue, which is reflected to the camera. A coupled phone, tablet, or computer receives and processes the time-of-flight measurement, the image, and the reflected grid of spots.
