水晶板对图像质量造成的异常现象早已为人所知。凭借其控制输出偏振的能力，激光器使得重新检查这些异常变得可行。使用双折射透镜，我们产生了空间上分离的多个图像。双焦点是通过利用薄晶状体中的普通光束和非常光束进行偏振控制来实现的。进一步的考虑表明通过电光控制实现 F = 2(n) 焦点的可能性，其中 n 是薄双折射透镜的数量。
The anomalies that crystalline plates introduce in the quality of an image have been known for many years. With its ability to control the polarization of its output, the laser makes reexamination of these anomalies practical. Using a birefringent lens, we have produced spatially separated multiple images. Dual focal points were achieved through polarization control by utilizing the ordinary and extraordinary beams in a thin crystalline lens. Further considerations indicate the possibility of achieving F = 2(n) focal points through electrooptic control, where n is the number of thin, birefringent lenses.
