Abstract: The invention relates to a spectrometry installation comprising an inlet, optical fiber means suitable for receiving an inlet beam and delivering a spectrally dispersed image of the beam which image is limited to a selected spectral band, a multi-channel detection module receiving said spectral image, and processor means. The optical filter means are provided with a deflector stage. Control means are associated with the optical deflector means to define the spectral band in terms of center frequency and band width, and control means are associated therewith for displacing the spectral image over the detection module. An electronic control unit is provided to control the control means and to control the processor means in a plurality of operating modes, each of which comprises joint control of the selected spectral band, of the displacement of the spectral image, and of the processor means, for the purpose of selectively using a particular set of detector components.

Abstract: A spectrometer using a CCD array in the time-delay integration mode is claimed. The spectrometer comprises a CCD having a plurality of charged-coupled devices disposed along a scan dimension which terminates at an output end of the CCD. Each device produces an electronic charge in response to electromagnetic radiation incident thereon. A monochromator, optically aligned with the CCD, has a diffraction grating which generates a plurality of spectral beams from an external source of electromagnetic radiation. The diffraction grating is movably mounted to sequentially scan the plurality of spectral beams. A control unit, coupled to the monochromator, controls the scanning operation of the diffraction grating and determines a scan rate for the spectral beams. The spectral beams are scanned along the scan dimension of the CCD during the scanning operation. A clock source, coupled to the CCD, sequentially shifts the electronic charge from one charge-coupled device to another along the scan dimension of the CCD at a shift rate substantially equal to the scan rate of the spectral beams. A serial shift register, coupled to the output, end of the CCD, accumulates the electronic charge as it is shifted to the output end of the CCD. An output amplifier, coupled to the shift register, produces a video signal from the electronic charge accumulated in the serial shift register. Each produced video signal represents an intensity value for a respective spectral beams.

Abstract: A sample (26) is illuminated by laser light and the resulting Raman spectrum (62) is dispersed at a high spectral resolution along one or more rows or columns of detector elements (60) of a CCD (34). The resulting charge is shifted in a direction Y′ and binned in an output register 64 of the CCD. The dispersed spectrum is moved along the rows or columns in a direction X′, synchronously with the shifting of charge in the output register (arrow 72). Thus, data from a given wavenumber in the spectrum continues to accumulate in the output register during the movement. This enables data from a wide spectrum to be collected at high resolution, without the need to subsequently stitch blocks of data together in a computer, even where the CCD is arranged such that row-by-row transfer of charge towards the output register is orthogonal to the direction of dispersion.

Abstract: An optical spectrum analyzer is provided with a user selectable sensitivity. Required operating parameters are set in response to user selection of sensitivity to permit measurement of an input light beam at the selected sensitivity. Setting the required parameters includes setting a required gain of a video channel to permit measurement of a specified maximum light signal and to provide the selected sensitivity, setting a required video bandwidth of the video channel to provide the selected sensitivity at the required gain of the video channel and setting a sweep rate to provide the selected sensitivity at the required video bandwidth. When the normal bandwidth of the video channel is not adequate to provide the selected sensitivity, the electrical signal is passed through a digital filter having a filter coefficient set to provide the required video bandwidth. A peak detector is incorporated in the video channel to accurately measure signal amplitudes in a fast scanning condition.
