美国Sandia国家实验室的D.J.Kane等人提出一种测量光脉冲强度和相位的方法。光源发出的光脉冲形成探测脉冲。选通脉冲单元产生可变时间延迟的选通脉冲。选通脉冲和探测脉冲在瞬时响应的非线性介质中合成,形成的信号脉冲与探测脉冲时间削波有函数关系。把信号输入到波长选通器件,输出信号脉冲信息由第一个时间延迟值的信号强度和频率组成。在有效值范围内,改变时间延迟便得到信号强度随频率和 D.J.Kane et al. At Sandia National Laboratory in the United States propose a method for measuring the intensity and phase of light pulses. The light pulse emitted by the light source forms a detection pulse. Strobe units generate strobes with variable time delays. The strobe and probe pulses are synthesized in a transient-response nonlinear medium and the resulting signal pulse is functionally correlated with the probe pulse time clip. The signal input to the wavelength gating device, the output signal pulse information from the first time delay value signal strength and frequency composition. In the range of effective values, change the time delay to get the signal strength with frequency and
