Abstract: Detection sensitivity of optical computing devices may be improved by utilizing multiple integrated computational elements in combination with one another. Optical computing devices containing multiple integrated computational elements may comprise: two or more integrated computational elements that are identical to one another and optically interact sequentially with incident electromagnetic radiation, such that at least a portion of the photons from the incident electromagnetic radiation optically interacts with each integrated computational element; wherein the sequential optical interaction of the incident electromagnetic radiation with the two or more integrated computational elements increases a detection sensitivity of the optical computing device relative to that obtained when only one of the integrated computational elements is present; and a detector that receives the photons that have optically interacted with each integrated computational element.

Abstract: Imaging spectrometers can be used to generate hyperspectral images for medical diagnoses, contaminant detection, and food safety inspections, among other applications. An exemplary imaging spectrometer includes an integrated position sensing array that measures the relative positions of the interferometer components based on an interference pattern generated by illuminating the interferometer with a reference beam. Such an imaging spectrometer includes a processor that controls the interferometer component position by actuating a voice coil and several piezo-electric elements to align the components with respect to each other and to provide a desired optical path length mismatch between the interferometer arms. In some cases, the processor may use feedback and feed forward control, possibly based on the actuators' transfer functions, for more precise positioning. The processor may also implement adaptive and recursive spectral sampling to reduce the image acquisition period.

Abstract: A measurement system includes semiconductor light sources generating an input beam, optical amplifiers receiving the input beam and delivering an intermediate beam, and fused silica fibers with core diameters less than 400 microns receiving and delivering the intermediate beam to the fibers forming a first optical beam. A nonlinear element receives the first optical beam and broadens the spectrum to at least 10 nm through a nonlinear effect to form the output optical beam which includes a near-infrared wavelength of 700-2500 nm. A measurement apparatus is configured to receive the output optical beam and deliver it to a sample to generate a spectroscopy output beam. A receiver receives the spectroscopy output beam having a bandwidth of at least 10 nm and processes the beam to generate an output signal, wherein the light source and the receiver are remote from the sample, and wherein the sample comprises plastics or food industry goods.

Abstract: The absolute spectral radiance of an unknown IR source is measured by bracketing the radiance measurements of the source over a spectral band with radiance measurements of a characterized blackbody at different temperatures. The absolute spectral radiance (or effective temperature) is calculated for the blackbody and paired with the relative radiance measurements. The absolute spectral radiance for the unknown IR source is derived via interpolation. The use of a characterized plate blackbody and a FTIRS allows for rapid and accurate characterization of the unknown IR source across a spectral band.

Abstract: A method is provided for monitoring one or more silicon-containing compounds present in a biogas. The method includes generating a first absorption spectrum based on a ratio of a first spectral measurement and a second spectral measurement. The first spectral measurement is from a non-absorptive gas having substantially no infrared absorptions in a specified wavelength range of interest and the second spectral measurement is from a sample gas comprising the biogas. The method includes generating at least one surrogate absorption spectrum based on, at least, individual absorption spectrum for each of a subset of one or more silicon-containing compounds selected from a larger set of known silicon-containing compounds with known concentrations. A total concentration of the one or more silicon-containing compounds in the biogas can be calculated based on the first absorption spectrum and the at least one surrogate absorption spectrum.
