摘要： Integrated computational elements having alternating layers of materials may be problematic to configure toward mimicking some regression vectors. Further, they sometimes may be inconvenient to use within highly confined locales. Integrated computational elements containing a quantum dot array may address these issues. Optical analysis tools with an integrated computational element can comprise: an electromagnetic radiation source that provides electromagnetic radiation to an optical pathway; an integrated computational element positioned within the optical pathway, the integrated computational element comprising a quantum dot array having a plurality of quantum dots disposed at a plurality of set array positions; and a detector that receives the electromagnetic radiation from the optical pathway after the electromagnetic radiation has optically interacted with a sample and the integrated computational element. Optical interaction of electromagnetic radiation with the quantum dots at one or more set array positions can substantially mimic a regression vector for a sample characteristic.

摘要： Technologies are generally described for determination and analysis of an optical profile of a liquid-based material to implement real-time monitoring of a composition of the liquid-based material for quality control. An imaging sub-system may include a plurality of illumination sources configured to illuminate the liquid-based material with light, and one or more detectors. The detectors may be configured to detect light reflected from a first surface of the liquid-based material, light reflected from a second surface of the liquid-based material, and/or light transmitted through the first surface and the second surface of the liquid-based material in response to the illumination. An analytics sub-system coupled to the imaging sub-system may be configured to analyze the detected light to determine an optical profile of the liquid-based material, and monitor the optical profile in real-time to detect changes in the optical profile indicative of corresponding changes to a composition of the liquid-based material.

摘要： A hyperspectral imaging system and methods thereof especially useful in fields such as medicine, food safety, chemical sensing, and agriculture, for example. In one embodiment, the hyperspectral imaging module contains a light source (1) for illuminating the object (6) in a light-tight housing (17). The light is spectrally filtered (4) prior to illuminating the object. The light leaving the object is then directed through imaging optics (T) to an imaging array (9). In another embodiment, the object of interest is illuminated by ambient light which is then compensated by a light modulation system. In this embodiment, the light emitted from the object is spectrally filtered prior to reaching the imaging array.

摘要： A gas analyzer system includes an optical source, an optical filter assembly, a controller, and an analyzer. The optical source generates an optical signal. The optical filter assembly includes different optical filters in which to filter the optical signal. During operation, the controller selects sequential application of each of the different optical filters in a path of the optical signal to modulate the optical signal using different frequency bands of optical energy. The modulated optical signal passes through an unknown sample. The optical analyzer analyzes the modulated optical signal after passing through the sample to detect which types of multiple different gases are present in the sample.
