A Fibre Optic Laser Doppler Anemometer, Data Acquisition System, and Analysis Procedure for Evaluating the Pre-Ignition Flow Field of a Motored Spark Ignition Engine
Published December 11, 1991 by Institution of Mechanical Engineers in United Kingdom
Laser Doppler anemometer system performance was enhanced by redesigning the frequency shifting system, and introducing fibre-optics to ensure optical stability and adaptability for motored engine flow field measurements. Ensemble averaging was used on the results from a data acquisition system.
