我们提出了一种方法，用于在二维（2D）波阵面的偏振状态的空间编码与椭圆偏振光控制椭圆的椭圆率和旋转角的主轴。我们已经构建了一个演示系统，使用两个光学可寻址的相位空间光调制器（SLM），它是可以控制的SLM中的每个调制单元的相对相位。这给出了一个完整的2D控制的偏振状态和结果的任意椭圆偏振的2D波前的产生。系统的实验性能进行了分析，并发现是在良好的协议与基于琼斯偏振矩阵法的理论分析。
We propose a method for spatially encoding the state of polarisation in a two-dimensional (2D) wavefront with elliptically polarised light controlling both the ellipticity and rotation angle of the major axis of the ellipses. We have constructed a demonstration system using two optically addressable phase-only spatial light modulators (SLMs), where it is possible to control the relative phase of each modulation cell in the SLM. This gives a full 2D control over the state of polarisation and results are presented for the generation of arbitrary elliptically polarised 2D wavefronts. The experimental performance of the system has been analysed and found to be in good agreement with a theoretical analysis based on the Jones polarisation matrix method.
