| Abstract: | We describe a new electro optic technique based on the linear electro optic effect for the measurement of freely propagating THz electromagnetic waves.The sensitivity and bandwidth of the electro optic crystal sensors are better than conventional photoconductive dipole antennas.The simplicity of the detection geometry and capability of optical parallel processing make these sensors suitable for real time 2D far infrared imaging. |
