We show the adaptation of a multifunctional optical system consisting of two spatial light modulators for the optimal measurement of the Radon-Wigner transform of one-dimensional signals. The proposed Radon-Wigner display allows reconstructing the Wigner distribution and the phase or the mutual intensity of fully or partially coherent fields, respectively. It is also suitable for the analysis of two-dimensional rotationally symmetric or separable in Cartesian coordinates optical fields. The feasibility of the proposed scheme is experimentally demonstrated in several examples.
我们展示了一种由两个空间光调制器组成的多功能光学系统的适应性，用于对一维信号的 Radon-Wigner 变换进行最佳测量。所提出的 Radon-Wigner 显示器允许分别重建 Wigner 分布和相位或部分相干场的互强度。它也适用于二维旋转对称或笛卡尔坐标系中可分离的光学场的分析。该方案的可行性在几个实例中得到了实验验证。
