Paper Abstract

Terahertz (THz) compressive imaging can obtain two dimensional image with a single or linear detector, which can overcome the bottleneck problem of lacking of THz two dimensional detectors. In this presentation, we propose a method to obtain two dimensional images using a linear detector. A plano-convex cylindrical lens is employed to perform Fourier transform and to encode one dimensional information of an object into wavelengths. After recording, both amplitude and phase information for different frequency at each pixel of the line detector are extracted, two dimensional image of the object can be reconstructed. Numerical simulation demonstrates the validity of the proposed method.
