摘要： A device including an integrated computational element (ICE) positioned to optically interact with electromagnetic radiation from a fluid and to thereby generate optically interacted radiation corresponding to a characteristic of the fluid, and a method for using the system are provided. The device includes a detector positioned to receive the optically interacted radiation and to generate an output signal proportional to an intensity of the optically interacted radiation. And the device further includes a processor positioned to receive the output signal and to determine the characteristic of the fluid.

摘要： Systems and methods of in-situ measuring the physical properties of an integrated computational element (ICE) device using surface acoustic wave (SAW) spectroscopy during fabrication are provided. The system includes a measurement device having a pump source providing an excitation pulse generating a SAW on the outer surface of the ICE. The system provides a probe radiation to be interacted with the outer surface of the ICE device and to form an interacted radiation, and an optical transducer configured to receive the interacted radiation and form a signal. An analyzer receives the signal from the optical transducer and determines a property of a material layer on the outer surface of the ICE device, and a second measurement device using at least one of optical monitoring, ellipsometry, and optical spectroscopy, is configured to measure a second property in the ICE device.

摘要： A design of an integrated computational element (ICE) includes (1) specification of a substrate and multiple layers, their respective target thicknesses and refractive indices, refractive indices of adjacent layers being different from each other, and a notional ICE fabricated based on the ICE design being related to a characteristic of a sample, and (2) identification of one or more critical layers of the ICE layers, an ICE layer being identified as a critical layer if potential variations of its thickness or refractive index due to expected fabrication variations cause ICE performance degradation that exceeds a threshold degradation, otherwise the ICE layer being identified as a non-critical layer. At least one critical layer of the ICE is formed using two or more forming steps to form respective two or more sub-layers of the critical layer, and at least one non-critical layer of the ICE is formed using a single forming step.

摘要： Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof. Additional apparatus, systems, and methods are disclosed.
