Title:
モダルメトリック・ファイバセンサ
Document Type and Number:
Japanese Patent JP2011515662
Kind Code:
A
Abstract:
A modalmetric fibre sensor comprises a multimode sensor fibre (26), a light source (14) for launching light into the multimode fibre (26) to produce a multimode speckle pattern of light at an end of the fibre (26), a single mode fibre (22) to receive light from the multimode speckle pattern and a detector (18) connected to the single mode fibre (22) to detect the received light from the multimode speckle pattern. A connector (33) connects the ends of the multimode fibre (26) and single mode fibre (22) with the end faces (31,32) of the two fibres disposed at an acute single to one another. The light from source (14) may be transmitted to the multimode fibre (26) through the single mode fibre (22) and the end of multimode fibre (26) remote from single mode fibre (22) may be mirrored to reflect light back along the multimode fibre to the single mode fibre which transmits the received light to the detector (18).
