We have designed, assembled, and evaluated a compact instrument capable of capturing the wavefront phase in real time, across various scenarios. Our approach simplifies the optical setup and configuration, which reduces the conventional capture and computation time when compared to other methods that use two defocused images. We evaluated the feasibility of using an electrically tunable lens in our camera by addressing its issues and optimizing its performance. Additionally, we conducted a comparison study between our approach and a Shack-Hartmann sensor. The camera was tested on multiple targets, such as deformable mirrors, lenses with aberrations, and a liquid lens in movement. Working at the highest resolution of the CMOS sensor with a small effective pixel size enables us to achieve the maximum level of detail in lateral resolution, leading to increased sensitivity to high-spatial-frequency signals.
我们设计、组装并评估了一种紧凑的仪器，它能够在各种场景下实时捕捉波前相位。我们的方法简化了光学设置和配置，与使用两个散焦图像的其他方法相比，减少了传统的捕获和计算时间。我们通过解决其问题并优化其性能，评估了在相机中使用电可调透镜的可行性。此外，我们对我们的方法与夏克-哈特曼传感器进行了比较研究。该相机在多个目标上进行了测试，如变形镜、有像差的透镜和移动中的液体透镜。在具有小有效像素尺寸的CMOS传感器的最高分辨率下工作，使我们能够在横向分辨率上实现最大程度的细节，从而提高对高空间频率信号的灵敏度。
