Aerospace Instrument-Making Annotation << Back AMPLITUDE FIBER OPTIC SENSORS N.M. Parfenov At present, automated systems for monitoring and controlling various technological processes, orientation and navigation systems for aerospace equipment, as well as monitoring hazardous vibrations in mines, tunnels, bridges and mine workings are being intensively developed. The operation of such systems requires the use of reliable high-precision fiber-optic sensors for measuring various physical quantities. Keywords: amplitude FOS, reflective and through-flow types, temperature, vibration. DOI: 10.25791/aviakosmos.9.2021.1240 Pp. 37-45.
