We propose an approach for implementing a modal wavefront sensor using a binary phase-only multiplexed computer-generated hologram (BPMCGH). To simplify the coding and fabricating processes, a model based on tilt plane reference waves and an effective coding scheme for BPMCGH have been developed. The necessary number of subholograms to be recorded or coded is significantly reduced, from two or even more to just one per aberration mode, accordingly. The numerical and experimental demonstration results are presented and discussed and show that this approach is convenient for producing a BPMCGH and efficient for sensing the aberration modes.
我们提出了一种使用二元纯相位复用计算机生成全息图（BPMCGH）实现模态波前传感器的方法。为了简化编码和制作过程，已经开发了一种基于倾斜平面参考波的模型以及BPMCGH的有效编码方案。相应地，要记录或编码的子全息图的必要数量显著减少，从每个像差模式需要两个甚至更多减少到仅一个。给出并讨论了数值和实验演示结果，结果表明该方法便于制作BPMCGH，并且在感测像差模式方面效率很高。
