Abstract: The present invention relates to a system and method for measuring a wavelength-resolved state of polarization, for calculating differential group delay of an optical signal under analysis (1) by means of taking multiple measurements of the spectrum of the signal under analysis (1) with spectral filtering means (3) with an optical output the power of which depends on the polarization of the input. The polarization at the input of the spectral filtering means (3) is modified by means of a polarization transformer (2) which sequentially selects a plurality of output states of polarization. The spectral filtering means (3) can comprise a filter based on stimulated Brillouin scattering amplification (10) simultaneously combining wavelength discrimination and polarization discrimination.

Abstract: A system and method for independently verifying a bank note processor's handling of circulating bank notes. Independent detectors are provided along the transport path of a bank note processing device. Also provided is at least one independent memory storage device for logging data from the independent detectors. As the note passes along the transport path, the independent detectors evaluate the note's fitness. The independent detector data is subsequently provided to the central bank or commercial organization for auditing of the bank note processor and for generating bank note statistics. Independent detectors may also be used on the transport path output bins to corroborate the other detectors and to verify the integrity of the sorting logic. Mirrored independent detectors allow for corroborating independent data. The invention is operable on any bank note processing device that performs at least a subset of a fitness determination on each note.

Abstract: This invention relates to a device and associated process capable of obtaining the optical spectrum phase of an optical signal or test signal to be analyzed using techniques for heterodyning between two monochromatic spectral components simultaneously extracted from the test signal itself by means of stimulated Brillouin scattering.
