Abstract :
Vectorial properties of a focused terahertz (THz) beam are measured by using a THz digital holographic imaging system. The THz transverse and longitudinal polarization components around the focal point are obtained utilizing the detection crystals with different crystalline orientations. This imaging technique provides an effective method for presenting the vector diffraction process of the THz wave.
