Optical and fiber-optic sensors (review)

Abstract

Optical, fiber-optic, and integrated optical sensors of physical effects are reviewed. The sensors are classified in accordance with their operating principle: amplitude, interference, and polarization sensors are considered. Descriptions are given of the construction of the sensors (or of their sensitive elements) which can react to mechanical quantities (displacement, force, acceleration), acoustic vibrations and pressure, electric and magnetic fields, electric current, temperature, angular velocity, etc. Some of their principal characteristics are described. Important parameters of known sensors are presented in a classified reference table.
