摘要
提出了基于邦加球轨迹的穆勒矩阵测量法,将极分解得到的矩阵与其在邦加球上的轨迹联系起来,通过输入光和输出光的偏振态在邦加球上的位置关系,直接获取非消偏元件的双折射矩阵和二向色性矩阵。结果表明:基于所提方法,偏振控制系统只需要一个可旋转起偏器,在测试前后提供两个确定的偏振态,即可直接获得光纤器件的双折射矩阵和二向色性矩阵,且在测量过程中无需改变待测光纤的状态。
Abstract
A measurement method of Müller matrix is proposed based on the trajectories on the Poincare sphere. A matrix obtained by the polar decomposition is related to its trajectories on the Poincare sphere. Therefore, the birefringence and dichroism matrices of a nondepolarizing unit are directly obtained via the position relationship of the input and output light polarization states on the Poincare sphere. The results show that, based on the proposed method, only one rotatable polarizer is required in the polarization control system. With the measurement of two polarization states determined before and after tests, not only the birefringence and dichroism matrices can be directly obtained, but also the state of the fiber to detect does not need change during the measuring process.
