A new optical implementation of the Radon-Wigner display for one-dimensional objects is presented, making use of the fractional Fourier transform approach. The proposed setup makes use of only two conventional refractive elements: a cylindrical lens and a varifocal lens. Although the exact magnifications cannot be achieved simultaneously for all the fractional transforms, an optimum design can be obtained through balancing the conflicting magnification requirements. Experimental results are obtained with a commercially available progressive addition lens. For comparison, computer simulations are also provided.
提出了一种利用分数傅里叶变换方法对一维物体进行拉东-维格纳显示的新型光学实现方案。所提出的装置仅使用两个传统折射元件：一个柱面透镜和一个变焦透镜。虽然不能同时为所有分数变换实现精确放大倍数，但通过平衡相互冲突的放大倍数要求可以获得优化设计。使用市售的渐进多焦点镜片获得了实验结果。为作比较，还提供了计算机模拟。
