该文以普克尔效应为基础，分析了ＬｉＮｂＯ３晶体在电场作用下的相位延迟，提出了光耦合双普克尔楔光学编码器的设计方法，从理论上分析了线偏振光经过光学编码器后，在远场空间不同偏振信号的图像特征，并对这些不同的偏振信号进行了解码研究
Based on the Pockels effect, the phase delay of LiNbO3 crystal under the action of electric field is analyzed. A design method of optically coupled double Pockels wedge optical encoder is proposed. The linear polarized light passes through the optical encoder After that, the image features of different polarized signals in the far-field are studied and these different polarization signals are decoded
