上世纪60年代激光刚被发现不久，其良好的相干性就被广泛用于测量设备的研制，在计量领域也以激光为工具建立了各类高水平计量标准，如米定义，几何量及运动量的基标准。半个世纪后的今天，冷原子技术使原子为代表的物质波具有良好的相干特性，它同样被立刻用于计量测试领域，法国计量院提供参与重力国际关键比对的冷原子重力仪就是最好的证明。本文以相干原理为主线，介绍了激光等电磁波在更高分辨力、更大空间范围以及更远物体的运动测量方面的进展，说明激光技术进展对动态测量领域开拓的重要引领作用，同时举例介绍了原子相干性在重力测量以及运动量动态测量中的重要作用。

Shortly after the laser was discovered in 1960's, its excellent interference was applied widely in measuring equipment manufac-ture, and many high-level standards were setup through laser in metrology field, for instance, meter definition, geometry and movement stand-ards. After half a century, cold atom technology provides good interference to matter wave, typically to atoms, which is immediately applied in measurement and metrology just like the laser, and the cold atom gravimeter is the best proof, which was provided by LNE to take part in the key comparison of absolute gravity. Centering on the principle of interference, the developments of movement measuring by laser towards higher reso-lution, larger space range, and more remote objects are introduced in this paper, which indicates that laser technology plays important role in the development of dynamic measurement. At the same time, the atom interference technology is introduced through the example of the cold atom gra-vimeter and the cold atom gyroscope, which shows superiority of atom interference in dynamic measurement of inertial parameters.
