IEEE 3101-2023

The scope of this document is to provide definitions and explanations of terms relating to the use of distributed acoustic sensor (DAS) interrogators. It also offers a list of key performance parameters critical to describe fully a DAS-based sensor system and to allow the end user readily to compare systems from different suppliers. Existing standards and definitions are used wherever possible. In addition, explicit links will be made between terms which are used commonly in internationally agreed metrology terminology.

The purpose of this standard is to clarify definitions so that ambiguity in specifications can be eliminated to facilitate broad usage of DAS sensing systems in a multiplicity of applications including smart civil structures, avionics, security, defense, transportation, energy, and environmental monitoring.

New IEEE Standard - Active. Terms critical to the use of fiber optic DAS interrogators along with key definitions of performance parameters used to both fully describe a fiber optic DAS based sensor system and readily compare systems from different suppliers are defined and explained in this standard.
