Optical fibre and application of this fibre to an optical device for remotely performing the chemical analysis of a body

摘要

The optical fibre 5 includes, from the centre to the periphery, a first core 10, a first cladding 11, a second core 12 and a second cladding 13. The device includes a laser whose radiation is transmitted to the body via the first core 10, the radiation scattered by the body being transmitted to an analysis device via the second core 12 of the fibre 5. Application to the remote metering of a mixture of liquids. IMAGE
