Transmission system for terahertz pre-amplified coaxial digital holographic imager

The application of terahertz wave holographic imaging technique in the study of the disease detection has attracted great interest. In this paper, a high-resolution terahertz coaxial digital holographic imaging transmission system operating at 3THz is presented. This design is used in the THz imaging system for the study of the disease detection. The physical optical propagation analysis method (POP) and an advanced three dimensional numerical calculation software MATLAB are used to analyze the results. The simulation results indicate that the design meet the requirement of the proposed system.
