Fiber Optic Sensors for Aerospace Applications
This document is intended to describe technologies available, application needs, and operational requirements relating to the use of fiber optic sensing systems on aerospace platforms: a. To define standard terminology used in describing fiber optic sensing systems and their performance. b. To identify current interfaces used for fiber optic sensing systems. c. To define environmental, reliability, and maintainability capabilities of fiber optic sensing system components. d. To describe the fiber optic sensor and instrumentation technologies that forms the current state of the art. e. To describe current and future unmet needs of the aerospace industry for measurements using fiber optic sensors.
The purpose of this document is to aid in sensor system selection for aerospace applications. It describes both generic and specific qualities of key fiber optic sensing technologies and the range of measurement tasks they are able to perform. This includes: • A critical and comprehensive comparison between specific optical sensor technologies, currently available, and corresponding non-optical sensing methods. This will assist aircraft component and subsystem designers to assess their suitability and potential for specific applications. • An appraisal of technology maturity levels and technology gaps. • Guidelines on the use and application of classes of fiber optic sensors are given including: o sensor and system compatibility (including fiber cable, connectors, interrogator, signal conditioning, network interface, and power requirements), o compatibility with aircraft systems, o standard forms of interrogation/interface, o proposed methods of standardization, and o qualification recommendations.
