在复ABCD矩阵理论的框架内，一个经典的飞行时间激光测速系统的时滞协方差的解析表达式作为激光光斑尺寸，限制孔径，和测量孔径半径的函数。推导并讨论了波前倾斜和速度失调的解相关效应。此外，误差估计表明如何以及可以确定的交叉协方差函数的峰值的精确位置。
Within the framework of complex ABCD matrix theory, an analytical expression for the time-lagged covariance of a classical time-of-flight laser velocimetry system is obtained as a function of the laser spot size, the limiting aperture, and the measurement-aperture radii. The decorrelation effects of wave-front tilt and velocity misalignment are derived and discussed. In addition, error estimates are presented that indicate how well one can determine the precise location of the peak of the cross-covariance function.
