We demonstrate the reconstruction of one- and two-dimensional objects by numerically backpropagating measured scattered terahertz transients. The spatial resolution determined by the Sparrow criterion is found to correspond to approximately 30% of the peak wavelength and 85% of the mean wavelength of the power spectrum of the single-cycle waveform.
我们通过对测量得到的散射太赫兹瞬态信号进行数值反向传播，展示了一维和二维物体的重建。发现由斯帕罗准则确定的空间分辨率大约对应于单周期波形功率谱峰值波长的30%和平均波长的85%。
