Abstract:
A spectral measurement method of the present invention includes: a measuring step of measuring optical spectra of some sections specified among a plurality of sections on a specimen; a scalar-value calculating step of calculating, for individual measured sections, scalar values that represent information contained in the obtained optical spectra; an interpolating step of interpolating scalar values of unmeasured sections by using the calculated scalar values and by using two types of interpolation methods; an identifying step of identifying sections in which absolute values of differences between the two scalar values interpolated by using the two types of interpolation methods are equal to or greater than a predetermined threshold; and a repeating step of re-executing steps from the measuring step to the identifying step after specifying the identified sections.
Abstract:
A system includes a computational system to receive a design of an integrated computational element (ICE) including specification of substrate and layers. Additionally, the system includes a deposition source to provide a deposition plume having a plume spatial profile, and a support having a cylindrical surface. The cylindrical surface of the support is spaced apart from the deposition source and has a shape that corresponds to the plume spatial profile in a particular cross-section orthogonal to a longitudinal axis of the cylindrical surface of the support, such that, when the substrate support, with the supported instances of the substrate distributed over the cylindrical surface of the substrate support, is translated relative to the deposition plume along the longitudinal axis of the cylindrical surface of the substrate support, thicknesses of instances of each of the deposited layers are substantially uniform across the plurality of instances of the ICE.

The present disclosure generally relates to systems, devices and methods for analyzing and processing samples or analytes. In one example configuration, a method of analyzing an analyte includes shaving a first layer of a plurality of layers of an analyte to expose a first surface of an analyte. The method includes positioning the first surface of the analyte over a window of a hyperspectral analyzation subassembly. The method further includes scanning the first surface of the analyte by the hyperspectral analyzation subassembly to obtain information regarding the analyte proximate the first surface. Other systems, devices and methods are disclosed herein.
Abstract:
A method for capturing hyperspectral images using a regular color camera. In the method, the camera takes multiple images of a scene, with the camera oriented differently for each image. For a camera carried by an aircraft or spacecraft, this allows hyperspectral imaging without the cost or weight of a hyperspectral camera.

The support is spaced apart from the deposition source and has a shape that corresponds to the plume spatial profile, such that when the supported instances of the substrate are distributed over the support, thicknesses of instances of each of the deposited layers are substantially uniform across the plurality of instances of the ICE.
Abstract:
Apparatus for performing Raman spectroscopy may include a first laser source having a first emission wavelength and a second laser source having a second emission wavelength. A separation between the first and second emission wavelengths may correspond to a width of a Raman band of a substance of interest. A switch may provide switching between the first and second laser sources. An ensemble of laser emitters may be provided. A Bragg grating element may receive laser light from the ensemble. An optical system may direct light from the Bragg grating element into an optical fiber. A combined beam through the optical fiber may contain light from each of the emitters.

Abstract:
The present invention provides a method of measuring a width of a color filter unit of a liquid crystal panel. The method includes providing a bottom glass substrate having a TFT array thereon; forming the color filter plate locating within an effective region of the liquid crystal panel by photo-etching process, and forming one or more measure modules locating of the liquid crystal panel and on the TFT array by the photo-etching process; and measuring widths of the one or more measure modules out of the effective region to obtain the width of the filter units within the effective region. The method provided is capable of effectively controlling widths of the color filter units formed in process of manufacturing the liquid crystal panel, thus quality of the liquid crystal panel is raised.
