Abstract:
A measurement system includes semiconductor light sources generating an input beam, optical amplifiers receiving the input beam and delivering an intermediate beam, and fused silica fibers with core diameters less than 400 microns receiving and delivering the intermediate beam to the fibers forming a first optical beam. A nonlinear element receives the first optical beam and broadens the spectrum to at least 10 nm through a nonlinear effect to form the output optical beam which includes a near-infrared wavelength of 700-2500 nm. A measurement apparatus is configured to receive the output optical beam and deliver it to a sample to generate a spectroscopy output beam. A receiver receives the spectroscopy output beam having a bandwidth of at least 10 nm and processes the beam to generate an output signal, wherein the light source and the receiver are remote from the sample, and wherein the sample comprises plastics or food industry goods.

Abstract:
A collision-computing system detects and amplifies the energy associated with a feature signal to determine occurrences or absence of events, such as ultrasonic and/or geophysical events, or to determine presence and/or concentrations of substances such as blood glucose, toxic chemicals, etc., in a noisy, high-clutter environment or sample. To this end, a conditioned feature, obtained by modulating a carrier kernel with a feature signal, is collided with a Zyoton—a waveform that without a collision can travel substantially unperturbed in a propagation medium over a specified distance. The conditioned feature and the Zyoton are particularly constructed to be co-dependent in terms of their respective dispersion velocities and the divergence of a waveform resulting from the collision. The collision operation can transfer at least a portion of the feature energy to the resulting waveform, and the transferred energy can be amplified in successive collisions for detecting/measuring events/substances.
Abstract:
Systems, methods, and apparatuses are provided for identifying an optimal spectral match and potentially display the compared spectra. A sample spectrum of a sample substance can be compared to reference spectra to identify matches, thereby determining possibilities for what the sample substance is. Correction parameter(s) may be used for the sample spectrum and/or the reference spectrum. Initial value(s) for the correction parameter(s) can be applied to the sample spectrum and/or a reference spectrum, and a similarity score can be determined. The value(s) for the correction parameter(s) can be updated and iteratively improved to provide an optimal similarity score that satisfies a convergence criterion. Data about the reference substances having optimal similarity scores that are above a threshold can be output to a user, e.g., the reference spectra can overlay the sample spectrum. A user can then make a final determination of which reference substance corresponds to the sample substance.
Abstract:
This invention provides a means for measuring a cholesterol content of a chicken egg by a non-destructive means. This invention relates to a method for measuring a cholesterol content of a chicken egg comprising: a step of light irradiation of irradiating the chicken egg with light in the visible to near-infrared wavelength range; a step of light detection of detecting light radiated from the chicken egg caused by that the light irradiated in the step of light irradiation is transmitted through the chicken egg or reflected inside the chicken egg; a step of spectrum acquisition of acquiring a near-infrared spectrum of the light detected in the step of light detection; and a step of cholesterol content determination of determining a cholesterol content of the chicken egg on the basis of the near-infrared spectrum acquired in the step of spectrum acquisition.
Abstract:
A spectroscopic method for spectroscopic detection and identification of bacteria in culture is disclosed. The method incorporates construction of at least one data set, which may be a spectrum, interference pattern, or scattering pattern, from a cultured sample suspected of containing said bacteria. The data set is corrected for the presence of water in the sample, spectral features are extracted using a principal components analysis, and the features are classified using a learning algorithm. In some embodiments of the invention, for example, to differentiate MRSA from MSSA, a multimodal analysis is performed in which identification of the bacteria is made based on a spectrum of the sample, an interference pattern used to determine cell wall thickness, and a scattering pattern used to determine cell wall roughness. An apparatus for performing the method is also disclosed, one embodiment of which incorporates a multiple sample analyzer.

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.
