李长胜 %A 崔翔 %J 光子学报 %D 1997 %I %X Based on the birefringence effect in some crystals, the pulse -- controlled polarization converter is advanced in this paper. It can convert the six polarization components of the polarized light into light intensity pulse by time--shared control system. The fundamental principle of the converter is presented. Generally, the pulse -- controlled polarization converter may be constituted by the electro--optic crystal with the dual transverse Pockels effect,the coded pulse electric field and the analyzer with a fixed direction. The different sensing signals contained in the different polarization components of the polarized light can be obtained by the converter and the time -- shared detection system through a single light path. This method can improve the sensitivity of signal detection and its anti--jamming. It is experimentally showed that the X,Y polarization components of the polarized light can be converted into light intensity pulses at a fixed direction by using a lithium niobate crystal and a pulse electric field. %K Polarization conversion %K Dual transverse Pockels effect %K Optical sensing signal detection
