Abstract: The invention relates to method for imaging measurement of a moving or flowing target and to an imaging measuring device for implementing the aforementioned nethod. Moreover, the invention relates to the use of information measured by means of imaging measurement in the control and/or adjustment of a process. According to the invention, electromagnetic radiation obtained from the moving or flowing target (T) is focused by means of imaging optics to produce an image to the screen of a two-dimensional matrix detector at least via a first and a second filter ( F1, F2) which transmit electromagnetic radiation in manners differing from each other. Said at least first and second filter form on the screen of the detector at least a first and a second filter area (FR1, R2) that partly cover the light-sensitive area (DA) of the detector. The properties of the target (T) are determined spectroscopically by comparing and/or combining spectrally resolved information, which is recorded when a pixel which corresponds to a determined part of the target kto be measured and is focused on the screen (DA) of the matrix detector without beamsplitting travels under the effect of the movement of the target (T) via said at least first and second filter area (FR1, FR2). The area of the screen (DA) of the detector remaining outside siad filter areas (FR1, FR2) is used for other kind of imaging non-spectroscopic measurement and/or visualization of the target.

Abstract: A multi-wavelength etalon suitable for tuning and maintaining the operating frequency of a laser used in an optical communication system is disclosed. The communication system has a representative channel wavelength and a channel spacing. The etalon has a plurality of steps on one of the sides with a step size that is a fraction of the channel spacing. The nominal thickness of the etalon is chosen so that a transmission peak occurs at a wavelength substantially equal to the representative channel wavelength and a next peak occurs at the wavelength of an adjacent channel. The step size is a fraction of the channel separation and is substantially optimized so that a peak or trough in the transmission curve in the region of one step overlaps a steep portion of the transmission curve for one or more other steps.

Abstract: Standardization is achieved for FTIR spectrometric instruments that effect an intrinsic distortion in spectral information, the distortion being associated with an aperture size. An idealized function of spectral line shape is specified. With a small calibration aperture, spectral data is obtained for a basic sample having known "true" spectral data, and standard spectral data also is obtained for a standard sample. With a larger, normal sized aperture, standard spectral data is obtained again for the calibration sample. A transformation factor, that is a function of this data and the standardized function, is applied to spectral data for test samples to effect standardized information. In another embodiment, the standard sample has known true spectral data, and the basic sample is omitted. In either case, the transformation factor is applied to the sample data in logarithm form, the antilogarithm of the result effects the standardized information.

Abstract: A compact spectroscope, particularly a sprectrofluoroscope or a microspectroscope, applicable for spectrophotometry of very slight light emission having a high visibility, overcoming the defects of the conventional spectroscope through the use of a transmission-type diffraction grating (G,55) and the combination of a two-dimensional photon counter (D,5Y) as an apparatus for obtaining the image of a very slight light emitting object. Light from a light emitting body is converted into a point or line source (S) and is specially detected by passing through a lens (L₁,54) having a small numerical aperture and a focus coincident with the source, a transmission type diffraction grating (G,55) and a collecting lens (L₂,56) to a detector (D,57).

Abstract: An acousto-optic frequency shifter having a long interaction region is used as an optical analyzer. A variable frequency signal generator (340) is used to drive an acoustic transducer (316) to launch an acoustic wave in contact with an optical fiber (300). The acoustic frequency is varied over a known range to generate acoustic waves having known wavelengths. An optical signal having an unknown optical wavelength is introduced into one end (302) of the optical fiber (300) in a first polarization mode. The effect of the acoustic wave on the optical signal is to cause coupling of the optical signal from the first polarization mode to a second orthogonal polarization mode. The amount of the coupling is dependent upon the phase matching between the acoustic wavelength and the optical beat length. The coupling between the polarization modes is maximum when the acoustic wavelength is equal to the optical beat length. The intensity of the optical signal coupled to the second polarization mode can be measured to determine the optical wavelength corresponding to the acoustic wavelength when the maximum intensity occurs.
