Paper Abstract

Fiber-optic sensors based on the amplitude modulation of the light guided by the fiber are considered. These can be sketched as an electro-optic module connected to the sensing tip by means of a multimode fiberoptic link. The problems related to the optical system and light propagation and those related to the referencing system and probe manufacturing are discussed and different solutions, depending on the working principle of the sensing tip, are proposed. Particular attention is given to the fiberoptic sensors designed and tested at IROE-CNR, which have been developed for the measurement of physical (temperature, proximity, vibration) and chemical (pH, bile refluxes) parameters.
