频率分辨光学选通作为一种将超短光信号完全表征为复杂电场的技术，存在几种方案和方法。然而，重建场的唯一性从未被证明。在这里，我们推导出的条件是足够的复杂脉冲的独特的重建。此外，我们构建了几个不同的脉冲对相同或基本相同的频率分辨的光门控轨迹的例子，甚至发现脉冲对的光谱强度相同的例子。
Several schemes and methods exist for frequency-resolved optical gating as a technique for the full characterization of ultrashort optical signals as complex electric fields. However, the uniqueness of the reconstructed fields has never been shown. Here we derive conditions that are sufficient for unique reconstruction of the complex pulses. Furthermore, we construct several examples of distinct pulse pairs with identical or essentially identical frequency-resolved optical-gating traces; even examples with identical spectral intensities of the pulse pairs were found.
