The feasibility of fast single-bit sampling for multi-point laser Doppler anemometry

A practical route is explored making use of high speed components for fast LDA signal sampling and storage, followed by fast Fourier transform signal analysis. A demonstration system is constructed consisting of ten optical channels arranged in a linear array, a single LDA sampling card and a contro...

Summary:A practical route is explored making use of high speed components for fast LDA signal sampling and storage, followed by fast Fourier transform signal analysis. A demonstration system is constructed consisting of ten optical channels arranged in a linear array, a single LDA sampling card and a controlling microcomputer. The arrangement is applied to a closed water circuit. (Original abstract-amended)
