  • NUMERICAL DATA PROCESSING DEDICATED TO AN INTEGRATED MICROSPETROMETER
    Publication number: 20070179729
    Abstract: A method and apparatus for obtaining higher resolution spectral data on lower-resolution spectral data provided by a spectrometric transducer is described. The method includes calibrating the spectrometric transducer to produce results for a reconstruction of spectra using the results, and processing the lower-resolution spectra data using a set of numerical algorithms dedicated to an integrated micro-spectrometers associated with the spectrometric transducer and using the results of calibrating to provide the higher resolution spectra data. The apparatus utilizes the method.
    Type: Application

  • Method of extracting spectral parameters of channels from non-channelized light
    Patent number: 6826331
    Abstract: A method of assembly is presented for a multi-wavelength optical monitor (MWOM) for use in fibre optic telecommunication networks. The method allows coarse optimisation to be used to align an input optical fibre and detector array relative to a wavelength division demultiplexing element. The detector array output data are transformed with a digital signal processor into relative intensities of the components of the spectrum or spectral parameters of telecommunication channels.
