When the third order dispersion effect exists, the more timedelaydifference is produced and the dispersion waves are produced at both the front and back edge of the pulse.
当只有三阶色散时，除了产生较大时延差外，还会在两个偏振脉冲的前后沿产生较大的色散波。

By using backward difference of space-time intensity correlation function with respect to time delay, the two-dimensional velocity vector of a moving diffuser can be measured.
利用远场时变散斑空-时强度相关函致的有限差商可以测量散射体运动的二维速度矢量。

The delay or difference in the arrival time of seismic events that can result from weathering of the rocks or variations in geologic structures in the subsurface.
