In this presentation, a system for THz en-face tomography imaging is proposed. The THz radiation reflected by the object is imaged on the ZnTe crystal, and then a CCD is used to detect the two dimensional modulated probe light. By adjusting the delay line, the information about the object can be achieved layer by layer. Expanded terahertz pulses are reflected from the different medium interfaces inside a sample, the amplitudes and time decays of these pulses can be used to determine the thickness of each medium inside the sample. In this way, the structure image of the sample can be reconstructed. The longitudinal resolution of the system is discussed by using the timing information of the reflection terahertz pulses.
