The focal length of a binary lens is linearly proportional to the frequency of the imaging beam; this property allows objects at various positions along the beam propagation path to be uniquely imaged on the same imaging plane with different corresponding frequencies. We reconstructed tomographic images of objects by assembling the frequency-dependent images, and demonstrated three-dimensional tomographic imaging using a binary lens with broadband terahertz pulses.
