    Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(mnullnullpnullr/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

    Abstract: A spectral rejection device for forming an image on an optical sensor, including a system for forming a beam of light rays coming from an observed scene, a scanning system, a system for spectrally dispersing the beam in a direction, at least one mask disposed on the path of the dispersed rays to intercept a narrow band of wavelengths, and a system for combining the dispersed rays into a beam of parallel rays focused by a lens onto an optical sensor. The invention applies in particular to the spectral analysis of a luminous flux coming from an observed scene.

    Abstract: An apparatus (1) including two plates (3, 4) which can be rotated in relation to each other and between which the rheological properties of a test substance (6) disposed in an intervening area (5) can be determined. At least one of the plates (3) is provided with a light inlet (2) sealed by a body (8, 10) in order to carry out an optical measurement method, e.g., infrared spectroscopy, enabling other characteristics of the test substance to be determined simultaneously. The body (8, 10) is light permeable at least in the infrared spectrum, and on its side facing the intervening area (5), the body (8, 10) terminates in a flush contour relative to the to the plate (3) in which it is provided so that undesirable interactions which might affect the measurement of the rheological properties of the test substance (6) are reliably excluded.
