Abstract: The disclosure provides a processing circuit adapted to read out a sensing voltage of an X-ray sensor and a signal processing method of a sampling circuit. The processing circuit includes an amplifier and the sampling circuit. An inverting input terminal of the amplifier is coupled to the X-ray sensor. The sampling circuit is coupled to an output terminal of the amplifier. The sampling circuit obtains a first voltage, a second voltage, and a sampling voltage of the X-ray sensor in different periods. The sampling voltage is between the first voltage and the second voltage. In the readout period, the sampling circuit subtracts the second voltage from the sampling voltage to obtain a third voltage, subtracts the second voltage from the first voltage to obtain a fourth voltage, and divides the third voltage by the fourth voltage to read out the sensing voltage of the X-ray sensor.

Abstract: A system for recording transmission spectra of a sample with a spectrometer that produces baseline-free molecular response signal. A method for producing baseline-free signals includes applying a logarithmic function to a measured transmission spectrum to form an intermediate spectrum. Applying an inverse Fourier transform to the intermediate spectrum generates a modified free-induction-decay (m-FID) signal, which allows for the separation of molecular absorption features from baseline effects present in the m-FID signal. A weighting function is then applied that suppresses temporal portions of the m-FID signal that correspond to sources of baseline fluctuations as well as periodic effects (e.g. etalons). The method generates a baseline-suppressed m-FID signal that is converted to an absorption spectrum, which exhibits suppressed contributions from baseline fluctuations and periodic effects.

Abstract: A characteristic of edible oil may be evaluated using a spectrometer. For example, optical reflectance data may be obtained from edible oil in situ in a frying apparatus housing the edible oil, the reflectance data corresponding to a specified range of infra-red wavelengths. A model profile corresponding to the characteristic being assessed may be obtained, such as from a repository housing a secured library of such profiles. The model profile may define a regression vector for use in transforming the reflectance data to generate a value corresponding to the characteristic being assessed. A criterion may be applied to the value to establish a simplified representation of the characteristic for presentation to a user for assessment of oil quality.

Abstract: A method for improving an image quality of X-ray tomograms includes generating a low-pass filtered X-ray tomogram by applying a low-pass filter to a two-dimensional X-ray tomogram. The low-pass filter is only applied to pixels with image values lying within a predetermined image value interval. A high-pass filtered X-ray tomogram is generated by subtracting the low-pass filtered X-ray tomogram from the two-dimensional X-ray tomogram. A Radon transform image is generated by calculating a Radon transform of the high-pass filtered X-ray tomogram. A modified Radon transform image is generated by modifying values of the pixels of the Radon transform image with values lying outside a predetermined value interval. A modified high-pass filtered X-ray tomogram is generated by calculating an inverse Radon transform of the modified Radon transform image. A modified X-ray tomogram is generated by the addition of the modified high-pass filtered X-ray tomogram to the low-pass filtered X-ray tomogram.
