标题： A Simple Method for More Precise Pulse-Height Fitting in Sparsely Sampled Data Using Pulse-Shape-Archetype Information, Especially Suited to Ultra-Short-Laser Pulsetrains

摘要： 本文提出了一种新颖的脉冲重构方法，非常适合用于稀疏采样的重复数据，例如通常来自超短激光脉冲序列的数据。 通常情况下，此类轨迹中的波形完全受到检测系统的限制，例如探测器和示波器的组合，仅寻求每个波形的能量。 当每个脉冲的波形形状相同且可以良好表征时，该方法适用，仅有幅度和相对峰值时间发生变化。 在这些条件下，此信息事先已知，可以作为非常精确的脉冲拟合的基础——原型。 我们的表征表明，即使采样通常错过脉冲峰值，甚至完全错过上升沿或下降沿，该方法也能非常准确地提取脉冲高度和相对脉冲时间。 我们展示了该方法在不同检测系统中的适应性，在此类问题中显著提高了测量的准确性。 显示英文摘要

摘要： This paper presents a novel pulse-reconstruction method well suited to sparsely sampled repetitive data, such as commonly arise from trains of ultrashort laser-pulses. Typically waveforms in such traces are fully instrument-limited by the detecting systems, for instance, the combination of detector and oscilloscope, and only the energy of each waveform is sought. The method applies whenever shape of the waveform is the same for every pulse and can be well-characterized, with only amplitude and relative peak-timing changing. Under such conditions this information, known in advance, can be used as a basis - an archetype - for very accurate pulse fitting. Our characterizations show that the method very accurately extracts pulse heights and relative pulse timing, even when sampling routinely misses the pulse peak, and entirely misses the rising or falling edge. We show this method to be adaptable in different detection systems, showing significant improvement in accuracy of measurement, in this class of problem.
