Abstract

Using Fourier optics, the conditions of the laser Doppler velocimeter (LDV) optimization in relation to the scattering center size, laser parameters, and photoreceiver aperture are found. The measurement errors are estimated for average and instantaneous velocities with regard to the statistics of the scatterers. The compensating scheme, which eliminates a low-frequency component of the signal and laser noise, is described. The results of its experimental applications are given.

摘要

利用傅里叶光学，找到了激光多普勒测速仪（LDV）在散射中心尺寸、激光参数和光接收器孔径方面的优化条件。根据散射体的统计特性，估计了平均速度和瞬时速度的测量误差。描述了消除信号低频分量和激光噪声的补偿方案，并给出了其实验应用结果。
