In dynamic measurement field, when using digital speckle pattern interferometry, we always deal phase with time-average method and spatial carrier phase-shifting method.

在动态测试领域中，数字散斑干涉技术常用到的相位处理方法有时间平均法和空间载波相移法。

Both theory and experiments show that stroboscopic shearing speckle interferometry is obviously superior to time-average method.

理论和实验都表明频闪剪切散斑干涉照相法要优于时间平均剪切散斑干涉照相法。

When you look into the details of these calculations (this is certainly true for HS2 in hte UK and I would be absolutely astonished if it is different elsewhere, as this is the standard method) the standard value ascribed to the time is the average pay of the people doing the travelling.
