Abstract

An optimal geometrical design procedure for a LDV system is derived. Its geometry is defined by the Gaussian f number of the lens F and the half-angle between the two beams θ. Parameters such as measurement volume size, the total broadening of the Doppler signal, the frequency limit of the processor, and some aspects of the signal strength are expressed in terms of these two variables. These parameters are then plotted as functions of F and θ on a single design chart.
