Synthetic phased-array terahertz imaging.
We demonstrate terahertz (THz) imaging with enhanced spatial resolution by a synthetic phased array. A single mirror is used to separately form two different coherent, diffraction-limited THz images of the same point source. The two images are combined to yield a 4x resolution-enhanced image of the source in one dimension.
