Fundamental relationships between backscattered power, range, wavelength, and number of scatter centers in the probe volume for the self-aligning, dual-scatter, laser doppler velocimeter are developed. It is shown that not all power scattered from the velocimeter probe volume contributes to a doppler signal. This fact leads to significant deviations in calculations involving signal-to-noise power ratios as compared to the case when only gross backscattered power is considered.
建立了自对准、双散射激光多普勒测速仪的反向散射功率、量程、波长与探测体积内散射中心数量之间的基本关系。结果表明，并非从测速仪探测体积散射的所有功率都对多普勒信号有贡献。这一事实导致在涉及信噪功率比的计算中，与仅考虑总反向散射功率的情况相比存在显著偏差。
