中文摘要：

以傅里叶变换极限脉冲作参考脉冲,利用单次测量分析法对复杂的皮秒脉冲进行测量,用窗口傅里叶变换代替傅里叶变换对干涉条纹进行时间-频率分析,直接提取出复杂脉冲的啁啾特性或光谱成分,将光谱图中的功率密度S（ω,t）沿ω轴求和重建脉冲的时域包络.分别用该方法和传统频域干涉测量法测量一个线性啁啾脉冲和一个复杂脉冲.结果表明,该方法可实现复杂整形脉冲的实时测量,且时间分辨率为70fs.

英文摘要：

A single-shot measurement and analysis technique with a Fourier transform limited pulse as a reference pulse was presented,which can be used for measuring the complex picoseconds pulses.Substituting the Fourier transform with a short time Fourier transform,a time-frequency analysis of the spectral fringe was achieved to directly extract the chirp characteristics or composition of complex pulse.Furthermore,the temporal envelope of pulse was reconstructed from the spectrogram by summing the power density S（ω,t）along the spectrumωaxis.To verify the utility of this method,this method and the traditional spectral interferometry was used to measure a linear chirped pulse and a complex pulse respectively.The results show that this method can be used to measure the characterization of complex shaped pulses in real-time,and with a temporal resolution of 70 fs.
