Abstract: A method of calibrating a hyperspectral imaging device includes illuminating a hyperspectral imaging sensor with a light source having known spectral properties, sampling the light from the light source with the hyperspectral imaging sensor to obtain sampled spectral properties, and calibrating a performance characteristic of the hyperspectral imaging sensor based upon comparing the sampled spectral properties of the light source to the known spectral properties.

Abstract: A small scale and low cost spectral sensing system designed primarily for multi-component fluids that provides a compact, low cost platform for analyzers or chemical sensors with limited number of optical and mechanical components featuring a light source, an optical interface with the sample, and a custom detector (multi-element). A single detector element has a specific wavelength, defined by a filter that can be used to select and measure specific chemical compounds. Multiple detector elements are combined to create a multi-channel detector capable of measuring a broad range of wavelengths from ultraviolet (UV) to near and mid-infrared wavelengths. The fabricated sensor can be configured for almost any class of material including gases, vapors, and liquids, with extension to solids. This is linked to the use of the custom detectors featuring filters tailored to specific substances in a broad spectral range from the UV to infrared.

Abstract: A method for spectral interpretation in absorption spectroscopy uses a nonlinear spectral fitting algorithm for interpretation of spectral features in complex absorption spectra. The algorithm combines two spectral modeling techniques for generating spectral models to be used in the curve fitting process: a line-shape model and a basis-set model. The selected models for all gas components are additively combined using a least squares minimization, allowing for quantification of multiple species simultaneously.

Abstract: A system and method of sorting mineral streams, for example laterite mineral ores, into appropriately classified valuable and waste streams for maximum recovery of value from the mineral stream, e.g., a stream of minerals includes receiving response data indicating reflected, absorbed or backscattered energy from a mineral sample exposed to a sensor, where the mineral sample is irradiated with electromagnetic energy. The system determines spectral characteristics of the mineral sample by performing spectral analysis on the response data of the mineral sample and identifies a composition of the mineral sample by comparing the spectral characteristics of the mineral sample to previously developed spectral characteristics of samples of known composition. The system then generates a sort decision for the mineral sample based on the comparison, where the sort decision is used in diverting the mineral sample to a desired destination e.g. pyrometallurgical treatment stages, or to a waste stream.

Abstract: For cavity enhanced optical spectroscopy, the cavity modes are used as a frequency reference. Data analysis methods are employed that assume the data points are at equally spaced frequencies. Parameters of interest such as line width, integrated absorption etc. can be determined from such data without knowledge of the frequencies of any of the data points. Methods for determining the FSR index of each ring-down event are also provided.
