Abstract: A method includes measuring (508) a caliper of a sheet (108) of material using a caliper sensor (200, 300) having first and second sensor modules (202-204, 302-304). The method also includes adjusting (514) the caliper measurement based on a transverse displacement between a first sensor component in the first sensor module and a second sensor component in the second sensor module to generate a corrected caliper measurement. Adjusting the caliper measurement can include applying a corrector function that adjusts the caliper measurement based on the measured transverse displacement. The corrector function can be identified by repeatedly creating misalignment between the first and second sensor components, measuring a known distance using the caliper sensor, and identifying an error between the measurement of the known distance and the known distance.

Abstract: Non-contacting caliper measurements of free-standing sheets detect mid-IR interferometric fringes created by the reflection of light from the top and bottom surfaces of the sheet. The technique includes directing a laser beam at a selected angle of incidence onto a single spot on the exposed outer surface and scanning the laser beam through a selected wavelength range as the laser beam is directed onto the exposed outer surface and measuring the intensity of an interference pattern that forms from the superposition of radiation that is reflected from the exposed outer surface and from the inner surface. Alternatively, the intensity of an interference pattern formed from the superposition of radiation that is directly transmitted through the web and radiation that is transmitted through the web after internal reflections from the internal surfaces of the web. Thickness can be extracted from the fringe separation in the interference pattern.

Abstract: Radiation scattering is one of the main contributors to the uncertainty of near infrared (NIR) measurements. Enhanced absorption-measurement accuracy for NIR sensors is achieved by using a combination of NIR spectroscopy and time-of-flight techniques to select photons that are the result of a given mean free path within a moving sample target. By measuring absorption as a function of path length or by windowing signals that are attributable to excessive scattering of NIR radiation within the sample, this technique affords the calculation of more accurate and more universal calibrations. The NIR sensor employs short or ultra-short laser pulses to create NIR that is directed to the moving sample and emerging radiation is detected over time. Windowing effectively truncates non-contributing measurements.

Abstract: A method includes measuring (304, 404) intensities of light passing through a sample (102) of an algae culture at different wavelengths. The method also includes identifying (204-206, 312, 416), using the measured intensities, a peak absorption wavelength of at least one type of chlorophyll in the sample and/or an absorption ratio involving multiple types of chlorophyll in the sample. The method further includes determining (210) whether the algae culture has a problem using the peak absorption wavelength and/or the absorption ratio. The peak absorption wavelength could be identified by identifying a specified wavelength at which a smallest amount of light passes through the sample. The absorption ratio could be identified by identifying (412) an average absorption wavelength of first and second types of chlorophyll in the sample and identifying (312) a peak absorption wavelength of the first type of chlorophyll.

Abstract: A method includes identifying (508) a chlorophyll concentration per optical density parameter (CCpOD) value (408) using a chlorophyll concentration measurement (504) of an autotroph culture (104) and an optical density measurement (506) of the autotroph culture. The method also includes identifying (510) a change in the autotroph culture using the CCpOD value. The change in the autotroph culture can be identified by determining whether the CCpOD value falls outside upper (404) and lower (406) control limits. The upper and lower control limits can be identified using a specified number of previously-determined CCpOD values, which can be calculated when the autotroph culture is in a known healthy state. Multiple CCpOD values can be calculated, and an alarm (120) can be generated if a specified number of the CCpOD values (such as one or more) fall outside the upper and lower control limits.

Abstract: A spectroscopic method (100) and spectroscopy system (200) therefrom for analyzing samples (298). A sample includes a first chemical component that has a characteristic first absorption peak is provided (101). The sample is irradiated (102) in a measurement waveband proximate to the first absorption peak, and at a first and a second reference waveband where the first chemical component lacks characteristic absorption features. Reflected or transmitted detection data is obtained (103) including a measured power proximate to the first absorption peak and first and second reference powers at the reference wavebands. A plurality of different waveband ratios are evaluated (104) using pairs of detection data to generate a plurality of measured waveband ratio values. A parameter of the first chemical component is then determined (105) by evaluating a multidimensional polynomial calibration equation that relates the parameter of the first chemical component to the plurality of different waveband ratios by substituting the measured waveband ratio values into the calibration relation.
