摘要：
Outline imaging by THz time domain spectroscopy is proposed. Spectroscopic splitting at interface is reported. The principle of outline imaging is put forward. Experimental results demonstrate the feasibility of outline imaging by spectroscopic splitting. It is shown that clear outline image of sample interface could be achieved easily by this technique. The spatial resolution is about 0.6mm. The THz-beam focus, the scanning step and the THz pulse width are the critical factors affecting the imaging resolution. The signal-to-noise ratio of this technique could be improved greatly compared to the conventional transmission imaging.
