摘要：
We present a focal plane terahertz (THz) ray imaging system through use of a big-size < 100 > oriented ZnTe electrooptic crystal plate. Some concealed living insects and moving objects have been directly imaged and the dynamic processes of the THz field distributions are clearly displayed, both in real-time model. We also discuss the maximum and minimum sizes of the available imaging objects in this THz imaging system, and give ways to improve them.
