Polarization Imaging of Liquid Crystal Polymer Using Terahertz Difference-Frequency Generation Source

We performed the polarization imaging of a liquid crystal polymer with a terahertz difference-frequency generation (THz DFG) source. The DFG source is an easy-to-operate and practical THz source. Liquid crystal polymers (LCPs) are suitable for applications such as fuel cell components, aircraft part...
