Abstract: 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.

Abstract: The invention provides an optical analysis system for efficient compensation of spectroscopic broadband back-ground, such as spectroscopic fluorescence background or background signals that are due to the dark current of a detector. The optical analysis system effectively provides multivariate optical analysis of a spectroscopic signal. It provides wavelength selective detection of various spectral components that are indicative of a superposition of spectroscopic peaks or bands and their broadband background. Additionally, the optical analysis system is adapted to acquire spectral components that predominantly correspond to the broadband background of the spectroscopic peaks or bands. Wavelength selective selection of various spectral components is performed on the basis of reconfigurable multivariate optical elements or on the basis of a position displacement of a spatial optical transmission mask.

Abstract: A method is presented to perform accurate property measurements using spectroscopic measurements at multiple wavelengths using nondispersed radiation with one, or sometimes two, detectors sensing all the requisite wavelengths simultaneously and calculating the value of the property by optical means. The heart of our invention is the utilization of an optical device opaque everywhere but at the finite and limited number of wavelengths where the transmittance measurements are being made, and whose transmittance at the measuring wavelengths is proportional to the coefficient for that wavelength in a predictive equation for the property value. The process which is our invention passes nondispersed light through a sample, with the transmitted light being led onto an optical device passing only the measuring wavelengths onto a detector. The optical device transmittances at the measuring wavelengths are proportional to the coefficients for those wavelengths, so that the total light passing through the optical device is actually proportional to the value of the property being measured. Our method leads to substantial reduction in instrument costs through simplified design and a reduction in components, with concomitant increased ease of use, and the elimination of the need for ancillary computational means.
