When a light pulse is made to follow a closed loop path in real space, the phase of the returning beam might be slightly off from the phase of light starting off at that point.
当一个光脉冲在一个真实的空间里沿着一个封闭的圆环运动，当它回到出发点时，其相位与刚出发时的相位可能会有些微的不同。
Starting a common trigger pulse, it can measure 64 event time intervals, and never loses them, which belong to simuta-neous events.
它由一个公共触发信号起动变换，可接受64路时间间隔的测量，对于多路同时事件不会造成事件丢失。
