Abstract: An image processing method of converting spectral image data of a plurality of spectral wavelengths imaged by a spectral camera into a color image by using a processor, wherein the processor acquires a plurality of pieces of the spectral image data from a storage unit, calculates a correction value by multiplying a optical spectrum of each pixel of a corresponding one of the plurality of spectral image data by a correction constant set for each wavelength, calculates a color conversion value by summing the correction values of the same pixel positions, and generates a color composite image based on the color conversion value. Then, the correction constant is set such that a sum spectrum obtained by summing characteristic spectra obtained by multiplying a sensitivity characteristic with respect to each spectral wavelength of the spectral camera by the correction constant corresponding to each wavelength matches a target spectrum of any color filter.

Abstract: Disclosed are a method and a device for reconstructing a spectrum, a spectrometer, a computer-readable storage medium, and an electronic device, and solves a problem of poor anti-noise ability of the method for reconstructing a spectrum. According to a feature that a spectrum must be positive, the present application converts the negative spectral value in the spectral data to be processed into positive spectral value by the objective function, so that the anti-noise ability of an iterative solution process of the objective function may be improved, and thus accuracy of the reconstructed spectral data may be improved.

Abstract: The present disclosure generally pertains to an imaging apparatus for computed tomography imaging spectroscopy, which has circuitry configured to:



obtain object image data being representative of light stemming from an object and being subject to an optical path and to a multiplexing process caused by a diffraction grating; and
perform a spectral density reconstruction from an image of the object by inputting the obtained object image data into an spectral density reconstruction algorithm being configured to numerically solve a first equation describing the transformation of the light stemming from the object caused by the optical path into the object image based on a reduction of a dimensionality of a first function indicative of the optical path based on a symmetry of the first function, thereby reconstructing the spectral density of the object.

Abstract: A spectrometer system may be used to determine one or more spectra of an object, and the one or more spectra may be associated with one or more attributes of the object that are relevant to the user. While the spectrometer system can take many forms, in many instances the system comprises a spectrometer and a processing device in communication with the spectrometer and with a remote server, wherein the spectrometer is physically integrated with an apparatus. The apparatus may have a function different than that of the spectrometer, such as a consumer appliance or device.

Abstract: Detection sensitivity of optical computing devices may be improved by utilizing multiple integrated computational elements in combination with one another. Optical computing devices containing multiple integrated computational elements may comprise: two or more integrated computational elements that are identical to one another and optically interact sequentially with incident electromagnetic radiation, such that at least a portion of the photons from the incident electromagnetic radiation optically interacts with each integrated computational element; wherein the sequential optical interaction of the incident electromagnetic radiation with the two or more integrated computational elements increases a detection sensitivity of the optical computing device relative to that obtained when only one of the integrated computational elements is present; and a detector that receives the photons that have optically interacted with each integrated computational element.
