Abstract: A system for determining a calibrated spectral measurement includes a tunable Fabry-Perot etalon, a detector, and a processor. The tunable Fabry-Perot etalon has a settable gap. The detector measures light intensity. The processor is configured to determine the calibrated spectral measurement. The calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a plurality of settable gaps and a reconstruction matrix. The reconstruction matrix is based at least in part on calibration measurements. For a calibration measurement, a settable gap is selected and a set of input monochromatic source wavelengths is used to measure responses at a detector after transmission through the Fabry-Perot etalon. Each input monochromatic source wavelength is also measured using a radiometer to scale detector measurements.

Abstract: The invention relates to a method and device for characterising at least one optical aberration of an optical system of an image acquisition device, the optical system having an associated optical transfer function that is dependent on the aberrations, the image acquisition device being capable of acquiring at least two images in a field of image capture in a manner so as to introduce a differential aberration between the two images, each image being defined by a digital image signal. The method includes the obtaining (50) of a first image and a second image of a same given zone of the field of image capture, the second image being acquired with a differential aberration (Δaberr) relative to the first image, each image acquisition having an associated optical transfer function. An optical aberration is characterised (58, 60) by the calculation of at least one parameter by minimisation of a functional expressed as a function of the first and second images acquired, from a modelling of the optical transfer functions associated with the two image acquisitions dependent on the aberrations of the image acquisition device as well as on the differential aberration (Δaberr).

Abstract: A method of calibrating a measuring apparatus includes determining apparatus parameters that have an influence on a measurement spectrum generated by the measuring apparatus, generating the measurement spectrum by exposing a measurement target on a sample to light generated by the measuring apparatus, calculating an error of the apparatus parameters by comparing the measurement spectrum to an ideal spectrum corresponding to the apparatus parameters, and calibrating the measuring apparatus based on the calculated error of the apparatus parameters.

Abstract: A method for improving dynamic range of a device for detecting light includes providing at least two detection regions. The detection regions are each formed by an array of a plurality of single-photon avalanche diodes (SPADs) and the detection regions each comprise at least one signal output. A characteristic curve is determined for each of the detection regions. The characteristic curves are combined with one another and/or offset against one another in order to obtain a correction curve and/or a correction factor.

Abstract: Aspects of the disclosure include suppression of optical interference fringes in optical spectra via a modification to the refractive index of media that forms or is contained in one or more components of equipment utilized for optical spectroscopy. Such a modification can yield changes in the optical path of light propagating through at least one of the media, with the ensuing changes in the spectral structure of interference between light propagating through different optical paths. In certain embodiments, the refractive index of the media that forms or is contained in one or more components can be modified via application of a time-dependent stimulus to at least one of the one or more components. The applied stimulus can include pressure, mechanical strain or stress, temperature, a combination thereof, or the like.

Abstract: A method and system for optimizing a match between the color of an in-line part manufactured by a plastic product production machine and the color of a reference part by adjusting the concentration of masterbatch in the mixture of raw material fed to the plastic product production machine. The optimization of the color is based on spectra of the in-line part and reference part obtained within a short time interval using the same spectrometer, thereby eliminating the requirement for high accuracy spectrometer calibration and allowing the method, which determines the rates at which the base masterbatches are added to the raw material, to be carried out in real time on the manufacturing floor while the plastic product production machine is being operated to manufacture in-line parts.

Abstract: An optical grain evaluation device is provided with: a light-projecting part 58 through which light from a light source is projected to grain; a light-receiving part 59 on which light transmitted through the grain is incident; a grain evaluation unit 60 configured to evaluate the grain based on information relating to the received light; and a shielding part SH that separates an area between the light source 50 and the light-projecting part 59 from an area between the light-receiving part 59 and the grain evaluation unit 60, and prevents light from the light-projecting part 58 from directly entering the light-receiving part 59. The area between the light source 50 and the light-projecting part 58, and the area between the light-receiving part 59 and the grain evaluation unit 60 are configured, over the entirety of the areas, as air transmission areas in which light is transmitted through air.
