Abstract
We present a multiwavelength phase imaging method for terahertz (THz) reflective focal-plane imaging. The phase of the THz pulse at each pixel is linearly fitted within the effective frequency range to reconstruct the ranging profile of the object. The results show that the multiwavelength method significantly improves the ranging resolution and imaging quality in THz reflective imaging applications.
