Experiments in Fluids (2005) 39: 954–965 DOI 10.1007/s00348-005-0012-x RESEARCH ARTICLE John Fitzpatrick Æ Laurent Simon Estimation of cross-power spectra using sample-and-hold reconstruction of laser Doppler anemometry data Received: 22 December 2003 / Revised: 8 June 2005 / Accepted: 8 June 2005 / Published online: 21 October 2005 Springer-Verlag 2005 Measurement of turbulent spatial and temporal length estimation of the spatial correlation of the turbulence so scales is an increasingly important aspect of analysis in that length and time scales can be estimated, and on the ﬂuid mechanics. This information is derived either from degree of correlation of the turbulence, with other dy- the cross correlation or the cross spectrum between two namic parameters. These properties are usually deter- measurements. The use of a laser Doppler anemometer mined from the normalised cross correlation or cross (LDA) further complicates the determination of these covariance function, but the use of the coherence func- properties because of the random data acquisition tion (normalised cross spectrum) and phase provides associated with LDA measurements. The calculation of considerably more information as they can also provide the cross spectrum obtained for LDA data with equi- information on the frequency dependence of the con- spaced data from
