Hardware and Software Integration for Concurrent Data Acquisition and Reduction of Photon Correlated Laser Doppler Velocimetry.

Abstract

A general Automatic Data Acquisition System dedicated to a broad range of experiments is used to operate the Digital Correlation signal processing equipment of a Laser Doppler Velocimeter, transfer data from the correlator into the Automatic Data Acquisition System computer and perform computations with the information. The Laser Doppler Velocimeter is used to acquire vast quantities of velocity and turbulence intensity information describing turbulent fluid flow about two dimensional airfoils. Integration of the velocimeter with the computer increases the capability of the system to perform large scale fluid dynamic studies.
