Abstract: The present disclosure provides for an apparatus for measuring optical properties of liquid samples. The apparatus includes a sample chamber and a spectrometer optically coupled with the sample chamber. One or multiple sources of electromagnetic radiation are positioned relative to the sample chamber to direct electromagnetic radiation through the sample chamber to measure the color, haze, and/or clarity of the sample. Also provided is a method for measuring optical properties of liquid samples, including inserting a cuvette containing a liquid sample into the sample chamber of the apparatus, and directing electromagnetic radiation from the one or more sources and through the sample to measure the color, haze, and/or clarity of the sample. The apparatus and methods may be used to analyze various samples, such as petroleum-based fluids, including fuels and lubricants.

Abstract: The present invention relates to the design, construction, and operation for a diode-turret. Exemplary embodiments comprise several tens of laser diodes to function as a multiple-line radiation source. The invention further describes the construction for a socket-turret; this socket-turret will flexibly fit any numbers (limited only by the number of sockets available) of laser diodes. The invention further describes two radiation coupling-optics for the output from the turret of laser-diodes, one with an integrating sphere and another with a collimating scope. One operation method allows its user to set for any number of diode, functioning one diode at a time, sequentially, hopping from one diode to another, as a single-line radiation source for the spectrometry. Another operation method permits its user to set a group with any number of diodes, functioning several diodes simultaneously at a time, as a multiple-line radiation source for spectrometry.

Abstract: A spectrometer, such as a Raman spectrometer, adapted for analyzing a complex sample is provided. In an example implementation, the spectrometer may be able to determine one or more spectral characteristics of an inner subsurface layer or region of a complex sample (e.g., contents of a container). In one embodiment, for example, A spectrometer includes an excitation source configured to provide an excitation signal; an optical system configured to direct the excitation signal toward a sample and receive a spectroscopy signal from the sample. The optical system may include a spatial filter configured to separate or isolate at least one first portion of the spectroscopy signal from at least one second portion of the spectroscopy signal and pass the at least one first portion of the spectroscopy signal. A detector is configured to determine at least one spectral feature of the at least one first portion of the spectroscopy signal.

Abstract: The present invention relates to a computationally compact and efficient method for determining physical characteristics of remote targets of interest from hyperspectral image scenes. Ground-based as well as space-borne hyperspectral imaging in the 7-14 microns region, also known as Thermal InfraRed (TIR) Hyperspectral imaging, is assuming increasing importance in military and civilian remote sensing. However, converting large hyperspectral imaging datasets into useable data products is complex and often requires long processing times. In-situ, field and on-board TIR hyperspectral imaging data processing is desirable for immediate detection, but currently very limited. Additionally, retrieving physical information of a target, seen against a background of clouds, is currently not possible. The present method creates a way to significantly improve the efficiency of analyzing hyperspectral imaging data to retrieve characteristics of remote targets of interest in the presence of both clear and cloudy sky background conditions. The present method uses a supervised machine learning Partial Least Squares Regression (PLSR) algorithm, which was trained from a library of simulated radiative transfer spectra. The radiative transfer library included a large number of complex conditions, which are difficult to implement in traditional lookup table methods, but become amenable in the present method. This invention is computationally compact and efficient and can be employed for on-board sensor data processing on the ground and in space. Various tests have shown the efficiency and reliability of the present method.

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 cold stage actuation system employs an optical assembly having an adapter ring mounted to a flange connected to a cold finger which extends into a Dewar housing. The flange supports a detector array. A resilient cold shield extends from the adapter ring to a lens holder, the lens holder connected to the resilient cold shield distal from the adapter ring. The lens holder supports a lenslet array. An optical light shield extends from the lens holder oppositely from the resilient cold shield to proximate a window in the Dewar housing. A motor is supported within the Dewar housing. An insulating translation arm connects the motor to the optical light shield, whereby operation of the motor induces the insulating translation arm to extend or retract the optical assembly concentric with an optical axis.

Abstract: A hyperspectral sensing device may include an optical collector configured to collect light and to transfer the collected light to a sensor having spectral resolution sufficient for sensing hyperspectral data. In some examples, the sensor comprises a compact spectrometer. The device further comprises a power supply, an electronics module, and an input/output hub enabling the device to transmit acquired data (e.g., to a remote server). In some examples, a plurality of hyperspectral sensing devices are deployed as a network to acquire data over a relatively large area. Methods are disclosed for performing dark-current calibration and/or radiometric calibration on data obtained by the hyperspectral sensing device, and/or another suitable device. Data obtained by the device may be represented in a functional basis space, enabling computations that utilize all of the hyperspectral data without loss of information.
