我们展示了一个时间成像系统，可以捕获事件与未知的到达时间在时域中，而不需要同步的信号。时间成像系统是基于时间透镜，它使用一个高重复率的光纤激光器的泵浦波与时间拉伸计划。在色散之后，相邻泵浦脉冲之间的定时小于脉冲宽度。因此，信号以高概率与泵浦脉冲之一相互作用，而不管其到达时间。我们讨论了这种成像系统的强度依赖性和时间像差，并演示了孤子的建立动力学的直接时间成像。
We demonstrate a temporal imaging system that can capture events with unknown time-of-arrival in the time domain without the need to synchronize the signal. The temporal imaging system is based on a time-lens that uses a high repetition-rate fiber laser for the pump wave together with a time-stretch scheme. After dispersion, the timing between adjacent pump pulses is smaller than the pulse width. Therefore, the signal interacts with one of the pump pulses with high probability, regardless of its arrival time. We discuss the intensity dependence and temporal aberrations of such an imaging system and demonstrate a direct temporal imaging of the buildup dynamics of solitons.
