Abstract:

Providing an introductory practical overview of in-flight optical flow measurement techniques is the goal of this AGARDograph. This document is written for instrumentation engineer or research scientist having a need for making non-intrusive flow measurements on an aircraft. It is hoped that this document will be particularly useful for the technologist with a limited background in optical theory and limited experience in applying optical technology. The experience of the authors and well as numerous other workers has been infused to provide guidance to avoid expensive non-productive diversions that may occur when applying optical technology for the first time in the flight environment. This AGARDograph provides basic knowledge and techniques necessary to assess the applicability of optical measurements and to address effective optical measurement techniques in flight. Key aspects of optical measurements are discussed and the tradeoffs are identified as they are currently understood. Basic components of optical measurement systems are discussed and key requirements are identified. Specific systems designed for a variety of applications are discussed to provide insight for the reader.
