    Abstract: The present invention relates to a method for monitoring and control of smeltmetallurgical processes, endothermic as well as exothermic ones, preferably pyrometallurgical processes, by means of optical spectrometry, whereby one first determines for each endothermic and exothermic smeltmetallurgical process and/or process step characteristic emissions or absorptions and identifies the atomic or molecular origin of the emissions/absorptions, that one during a running process records changes in the characteristic emissions/absorptions and relates these changes to the condition of the process and with reference hereto controls the process.

    Abstract: Color former is added to blood serum sample color it, and measurements for specific components are determined based on the light absorbance caused by coloring. For one sample, a differential light absorbance between two wavelengths at each of long wavelength region, middle wavelength region and short wavelength region within a visible wavelength band is determined. The degree of chyle is determined from the measurements for the long wavelength region, the degree of hemolysis is determined from the measurements for the middle wavelength region, and the degree of icterus is determined from the measurements for the short wavelength region. The measurements for the specific components are then corrected by the degree of chyle, degree of hemolysis and degree of icterus to obtain highly correct measurements.

    Abstract: A plurality of test tubes containing specimens are passed successively through a predetermined position. Two monochromatic beams are transmitted alternately along a single path through said predetermined position and through each of the test tubes passing through said predetermined position. The characteristics of the two beams are such that one of them is capable of being absorbed by the specimen and the other substantially incapable of being absorbed. Thus it is possible to obtain an electric signal representing the ratio or difference between electric signals corresponding to said two monochromatic beams.

    Abstract: A beam of light passes through a sample and the transmitted light beam is detected by a detector. The light beam to be detected by the detector is a monochromatic light beam obtained by a dispersing means and the wavelength of the monochromatic light beam is continuously varied by a wavelength scanner. A transparent plate is obliquely positioned in the path of the monochromatic light beam so that the detector delivers an electrical signal representative of the absorption when the transparent plate lies in the path of the light beam and another electrical signal representative of the absorption when the transparent plate does not lie in the path of the light beam. A ratio detector or a difference detector compares these electrical signals with each other or subtracts one of these electrical signals from the other thereby obtaining a differential spectrum.

    Abstract: An interference fringe pattern generator form's an interference fringe pattern from the light rays diffused from a region of an object positioned against a background. A planar array of detector pixels is arranged to capture an image of the interference fringe pattern. A storage medium records information indicative of intensity values of the image of the interference fringe pattern captured by a selected group of pixels of the planar array of detector pixels. The information is recorded as a function of the optical path difference values traversed by the diffused light rays through the interference fringe pattern generator for each of the pixels in the selected, group of pixels. A processor determines the spectral characteristics of the object based on the information indicative of the intensity values recorded by the storage medium and the optical path difference values traversed by the diffused light rays.
