Performance of fiber optic sensors for aircraft applications

摘要

Measured performance is presented for passive fiber-optic sensors including a rotary position sensor, a pressure sensor, and a temperature sensor. A liner position sensor derived from the principles of the rotary sensor is also presented. The use of a common sensing principle utilizing wavelength-division multiplexing is detailed. The requirements for the light source and receiver/decoder and the current status of development are discussed. Environmental performance data for the rotary sensor system are given.
