【摘要】 介绍了一种基于调制偏振光的空间正交方位信息传递系统。系统利用调制和解调传递一个正交方位,用电光晶体对偏振光进行调制,电光晶体的感生主轴方向构成发射部分的基准方位。接收部分利用Wollaston棱镜和光电转换器进行解调,由感生主轴构成的基准方位和Wollaston棱镜的两正交光轴之间的夹角信息反映了正交方位传递的精确性。更多还原

【Abstract】 A system of azmuth information transmitting is introduced.At the launcher,a Pockles cell generates modulated polarization light.Induced principal axis of electro-optical modulator makes the datum azmuth.The signal is demodulated by a Wollaston prism and a receiver.Angle between the induced principal axis of Pockles cell and orthogonal optical axis of Wollaston prism indicates the accuracy of azmuth information.更多还原
