给出了用慢检波器完全测量脉冲电场幅值和相位的仪器性能的一般条件。特别是，它示出了一个超短脉冲形状的表征的一个必要和充分条件是，该装置由至少一个时间非平稳和一个时间固定的元素。我们表明，只有四种可能的noninterferometric计划，满足这一标准。我们分别讨论这四个最小的方法和相关的算法重建的脉冲形状从测量数据。
Some general conditions concerning the properties of apparatuses that can measure completely the amplitude and the phase of a pulse’s electric field by using a slow detector are formulated. In particular, it is shown that a necessary and sufficient condition for the characterization of an ultrashort pulse shape is that the apparatus consist of at least one time nonstationary and one time stationary element. We show that there are only four possible noninterferometric schemes that meet this criterion. We discuss separately these four minimal methods and the associated algorithms for reconstructing the pulse shape from the measured data.
