Automatic calibration of LDA measurement volume size.
The problem of particle number density measurements with a laser Doppler anemometer is addressed. Analytical expressions for the instrument measurement cross section are given. An automatic calibration method for determining unknown scattering parameters, which promises good accuracy in changeable optical conditions, is described. Estimates of the measurement uncertainty are derived and the method is extended to uses in 2-D flow fields.
