Paper Abstract

Polarization information detecting can obtain more useful knowledge of objects than traditional intensity detecting, its merits have been paid special attention to by remote sensing especially by disguised objects detecting. At present, the way to get objects' polarization state is achieving four intensities by mechanically rotating phase delayer to measure the Stokes vector, which can describe objects' polarization state. Modulating coherent waves' phase difference with electro-optical effect to achieve four intensities and inversing objects' polarization information is proposed in this paper. This method can avoid the traditional mechanical rotation's lack of stability and reliability, which has the remarkable advantages in space detecting and remote sensing. Experiments have been done to verify the correct and feasibility of this approach. The key technical points in this approach are presented in the end.
