摘要：

We have designed, fabricated, and characterized a real-time multi-spectral T-ray imager based on a hybrid metamaterial focal plane array (FPA). The heart of the imager is a multi-spectral terahertz metamaterial detector operating at 2.5 THz, 3.4 THz and 4.3 THz, respectively. The prototype FPA consists of 4 x 4 image pixels, which can be easily scaled up for a larger array. As a proof of concept, we have performed real-time 2D imaging for objects whose sizes are comparable to the detector array. For scanning imaging, a spatial resolution of 350 mu m has been achieved.
