Optimization of LDV geometry.
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 theta. Parameters such as measurement olume 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 theta on a single design chart.
