| 摘要 |
The invention relates to a system and a method for distributed sensing and metrology which allow the characterisation of an optical fibre means (102) branched by means of wavelength multiplexing. The system comprises light emission means (100) suitable for emitting light of multiple wavelengths (λ1, λ2, λ3) and routing means (106a, 106b) suitable for distributing said wavelengths (λ1, λ2, λ3) in a plurality of segments (105a, 105b, 105c, 105d, 105e) of the optical fibre means (102). The system also comprises detection means (103) and analysis means (104) suitable for characterising each segment (105a, 105b, 105c, 105d, 105e) according to a light resulting from a propagation of at least one wavelength(λ1, λ2, λ3) via said segment. |
