为了实现高隔离度的收发隔离的目的,采用了一种偏振收发隔离光学系统的方法,利用琼斯矩阵对其进行了理论分析,验证了偏振隔离在收发同轴光学系统中的可行性。采取空间隔离来抑制回波进入接收系统,模拟系统中偏振分束镜前表面楔角大小对收发隔离度的影响,在达到一定楔角时,取得了100d B收发隔离度。这一结果对收发同轴光学系统设计具有一定指导意义。
In order to achieve the purpose of high isolation transceiver, a method of polarization transmitting and receiving optical system is proposed. The theoretical analysis is carried out by using Jones matrix to verify the feasibility of polarization isolation in the receiving and sending coaxial optical system. Space isolation is adopted to restrain the echo from entering the receiving system. The influence of the wedge angle of the front surface of the polarization beam splitter on transmitting and receiving isolation is simulated. When a certain wedge angle is reached, 100d B receive and receive isolation is achieved. This result is of guiding significance for the design of the coaxial optical system.
