A correlation method for determining the number of sampling cycles required for pulsating flow analysis using a LDA.

A correlation method has been developed for pulsatile flow analysis, which allows justification of the minimum number of cycles for ensemble averaging, to satisfy ergodicity. It can also be used to identify cycles with excessive fluctuations caused by artefact or incidental errors and, hence, enhance the accuracy of analysis.
