介绍了一种简单而通用的技术，用于恢复一个给定的光波形的相位分布从时间强度测量和实验证明。所提出的方法涉及的线性光学时间微分器的输入和输出的时间强度分布的测量。可以使用直接且非迭代算法从这些强度测量中明确地恢复信号相位轮廓。鉴于超快光学微分器可以很容易地在全光纤或自由空间平台中实现，所提出的技术可以应用于持续时间从亚皮秒到纳秒范围的时间波形。(c)2007年，美国光学学会。
A simple and general technique for recovering the phase profile of a given optical waveform from temporal intensity measurements is introduced and experimentally demonstrated. The proposed method involves the measurement of the temporal intensity profiles at the input and output of a linear optical time differentiator. The signal phase profile can be unambiguously recovered from these intensity measurements using a direct and noniterative algorithm. Given that ultrafast optical differentiators can be readily implemented in all-fiber or free-space platforms, the proposed technique could be applied over time waveforms with durations ranging from the subpicosecond to the nanosecond regime.
