Patent ID: 8126326

Claim:
A device for the analysis of the optical spectrum phase comprising: a) an optical source (SUR) generating an optical probe signal formed by at least two controlled spectrum separation monochromatic lines (DMS) that can move along the spectral range to be measured; b) a high resolution optical spectrum analyzer based on stimulated Brillouin scattering (SBS) in which a test signal (SUT) to be measured and said at least two monochromatic lines of the probe signal (DMS) interact with each other, producing a diffused optical signal (DOS) formed by two spectral lines; c) a photoelectric detection system (HF) in which a heterodyne effect between said at least two spectral components (DOS) occurs and which provides at its output a detected electrical signal (DES); d) a module acting as an electric phase analyzer (EPA) for extracting the phase information of the mentioned test signal (SUT) contained in said detected electrical signal (DES); and e) a data processing unit (CPU) for processing the signals and controlling the different elements of the device.
