Abstract
We report the demonstration of two-dimensional electro-opticimaging using continuous-wave THz radiation. Two single-frequency laser diodes serve as the optical source for both the generation and detection processes. The generation process occurs by mixing in a photoconductive emitter, while the detection process utilizes an electro-optic crystal and charge coupled devicecamera. The method permits far-IR imaging using only conventional optical components held at room temperature. In this demonstration, we image the two-dimensional properties of a THz beam focused into a 〈110〉 ZnTe electro-optic detection crystal.Keywords
