    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 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.

    Abstract: A spectroscopy system for auto-aligning a biopsy collecting device is presented. The spectroscopy system includes an illumination subsystem configured to emit an illumination light towards the biopsy collecting device, whereas the biopsy collecting device includes an activator unit and a needle unit and wherein the needle unit includes a cannula and a stylet having a biopsy specimen. Also, the spectroscopy system includes a fixation subsystem capable of holding the biopsy collecting device and configured to place the needle unit comprising the biopsy specimen across the illumination light. Further, the spectroscopy system includes a detection subsystem configured to receive a light comprising at least one of an attenuated illumination light and a re-emitted light from the needle unit. In addition, the detection subsystem is configured to send a control signal to align the needle unit at a predetermined position in the spectroscopy system based on the received light.
