Abstract

A method to analyze the variety of the polarization state of terahertz (THz) wave by using a typical electro-optic sampling setup with 〈110〉 zinc-blende (ZnTe) crystal as a sensor is presented. To illustrate the knowledge of polarization of the THz pulse, the function of THz detect in ZnTe crystal is interpreted. Two kinds of Jones matrixes, birefringence device and polarizer device, are used to analyses the polarization change of the THz electric field vector caused by the sample. It was found that the THz polarization imaging is sensitive to the edge of the samples.
