ARP6366 defines a comprehensive and widely-accepted set of specification guidelines to be considered by those seeking to use or design fiber optic sensors for aerospace applications. Some of the most common applications for fiber optic sensing within aerospace include inertial guidance and navigation (gyros) and structural monitoring (temperature, strain, and vibration sensing). Common sensor infrastructure elements include: transmitting and receiving opto-electronics (e.g., sources and receivers); multiplexing and demultiplexing optics; optical cabling; and signal processing (both hardware and firmware/software). Use of fiber optic sensor systems in the aerospace industry is expected to grow as the benefits and unique sensing solutions are understood. Guidance is needed for writing fiber optic sensor specifications to supply a comprehensive and widely-accepted vocabulary, parameters, and practices for fiber optic sensors for aerospace applications. Adoption of fiber optic sensors on aerospace platforms will benefit from improved coordination between developers, specifiers, program managers, and end users.

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: aTo define standard terminology used in describing fiber optic sensing systems and their performance. bTo identify current interfaces used for fiber optic sensing systems. cTo define environmental, reliability, and maintainability capabilities of fiber optic sensing system components. dTo describe the fiber optic sensor and instrumentation technologies that forms the current state of the art. eTo 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: sensor and system compatibility (including fiber cable, connectors, interrogator, signal conditioning, network interface, and power requirements), compatibility with aircraft systems, standard forms of interrogation/interface, proposed methods of standardization, and qualification recommendations.

The purpose of this document is to serve as a resource to aerospace designers who are planning to utilize Wavelength Division Multiplexed (WDM) interconnects and components. Many WDM commercial systems exist and they incorporate a number of existing, commercially supported, standards that define the critical parameters to guide the development of these systems. These standards ensure interoperability between the elements within these systems. The commercial industry is motivated to utilize these standards to minimize the amount of tailored development.However, since some of the aerospace parameters are not satisfied by the commercial devices, this document will also try to extend the commercial parameters to those that are necessary for aerospace systems. The document provides cross-references to existing or emerging optical component and subsystem standards. These parameter definitions, test methods, and procedures typically apply to telecommunications application and in some cases may require refining to adapt them to aerospace optical network and system applications. As aerospace fiber optics engineers turn to wavelength divison multiplexed fiber optic technology for advanced network implementations, it is important that any standards produced agree and build on standards that already exist. This document seeks to leverage the standardization effort made by the telecommunication industry and identify how their efforts apply to aerospace applications.

FIBER OPTIC SENSORS Discover the latest in fiber optic sensors and their applications in this new edition Fiber-optic sensors are a powerful class of sensor that uses high-bandwidth optical fibers to convey a large amount of measured information through a single fiber. The advantages of such a mode of measurement are clear: they are intrinsically safe in explosive environments (no sparks), lightweight, compact, robust, and potentially inexpensive. As a result, their uses are manifold for a wide range of physical and chemical phenomena including temperature, strain, pressure, acoustic fields, position, velocity, rotation, acceleration, electrical current, liquid level, biochemical composition, and chemical concentration. Fiber Optic Sensors introduces and familiarizes the reader with a broad range of fiber optic sensor techniques and applications. The latest edition of this popular text builds upon the sound introductions to the fundamentals of the topic provided by earlier editions by introducing the latest technologies that have been developed in recent years. Gathering the latest research and publications on the subject in one place, the book provides a comprehensive look at fiber optic sensors with an eye to what’s new in the field.

This SAE Aerospace Information Report (AIR5271) covers the basic attributes of a second-generation robust, reliable high-density fiber optic interconnect system for aerospace applications. The intent is to take advantage of recent commercial developments in materials, components and manufacturing methods to develop rugged high-density fiber optic interconnects optimized for aerospace and automotive applications, which can accommodate a variety of optical fiber waveguide types. These waveguide types include single mode and multi-mode glass/glass fibers and waveguides, plastic clad silica fibers and waveguides, and all polymer fibers and waveguides. This second generation interconnect system should represent a dramatic improvement over first generation. The cable should be extremely robust eliminating any concerns over cable damage or fiber breakage in an aerospace environment.A high-density fiber optic interconnect system provides the physical medium for optical data and control communication in aerospace vehicles. As such, it consists of the cables and harnesses, connectors, splices, backplane interfaces, transceivers, fiber optic couplers, and includes test and maintenance concepts for these items. Also included are manufacturing, installation and repair tools, processes and training programs. The high-density format should provide for both redundant serial data transmission or parallel data transfer by providing a scaleable fiber count. Connectors should provide an extremely small footprint, with low mass connector shells and array inserts, and accommodate both single and multi-mode fibers. Fiber spacing and cladding diameter should be standardized and coatings utilized to guarantee long term reliability. The cable connector interface shall be optimized to preclude damage during installation and/or maintenance actions as well as ease of termination. All elements of the cable plant should be compatible including splices and couplers with minimum weight, volume and footprint. This optimized cable plant shall serve as an integrated information distribution system capable of transferring all information on military and commercial aircraft with dramatic improvements in affordability, reliability, fault tolerance, EMI/EMP immunity and safety. Utilization of this cable plant will improve aircraft performance and fuel economy, providing operational cost effectiveness while reducing new aircraft certification costs.
