Abstract: A single Integrated Computational Element (“ICE”) predictive of multiple sample characteristics.

Abstract: A method controls fabrication of a multi-layered integrated computational element designed to have a target optical spectrum. A transfer function is generated relating a blue wavelength, shift between an as-annealed optical spectrum and an as-fabricated optical spectrum of a first integrated computational element at a standard temperature. Using the transfer function, an initial compensating red shift is incorporated into a second integrated computational element such that the as-annealed optical spectrum of the second integrated computational element matches the target optical spectrum.

Abstract: An optical computing device utilizes an Integrated Computational Element (“ICE”) core to correct calibration transfer errors in the device.

Abstract: Disclosed are optical design techniques for generating environmentally resilient optical elements used in optical computing devices. One method for designing an integrated computational element (ICE) includes generating a plurality of theoretical ICE designs with a design suite stored on a non-transitory, computer-readable medium, each theoretical ICE design being configured to detect a characteristic of interest and comprising one or more layers, sorting the theoretical ICE designs based on performance criteria of each theoretical ICE design and thereby identifying one or more predictive ICE designs, calculating a theoretical effect of a temperature shift on each predictive ICE design, and selecting for fabrication one or more predictive ICE designs based on favorable temperature stability.

Abstract: Disclosed is apparatus and methodology for producing thermal detectors with spectral responsivities that mimic the absorptions of chemical analytes, and whose detector characteristics approach those of conventional broad-band thermal detectors. In an exemplary arrangement, the methodology provides for modification of a known Si-based thermal detector by adding a near-infrared dye absorbing film above a reflector deposited directly on the thermal detector element. The method is general to all types of thermal detectors that can be divided into separate absorber and thermal sensor components.
