Abstract

Azimuthal shear interferometry is a versatile tool for analyzing wavefront asymmetries. However, conventional systems are bulky, alignment-sensitive, and prone to nonuniform shear. We present a broadband, compact, and robust meta-optics-based azimuthal shear interferometer in a common-path configuration, reducing the system size to the millimeter scale. Unlike conventional designs, the meta-optic azimuthal shear interferometer utilizes the localized wavefront modulation capabilities of meta-optics to achieve uniform azimuthal shear displacement independent of the radial position, significantly enhancing accuracy and stability. Our approach eliminates the need for bulky optical components and precise multipath alignment, making it more resilient to environmental disturbances. Its multifunctionality is demonstrated through applications in all-optical edge detection, differential interference contrast microscopy, and aberrated wavefront sensing. These results underscore its potential for real-time analog image processing, advanced optical imaging, and optical testing.

多功能元光学方位剪切干涉仪

方位角剪切干涉法是一种分析波前不对称性的通用工具。然而，传统的系统体积庞大，对对准敏感，并且容易发生不均匀剪切。我们提出了一种宽带、紧凑、鲁棒的基于元光学的共路配置方位剪切干涉仪，将系统尺寸减小到毫米级。与传统设计不同，元光学方位角剪切干涉仪利用元光学的局部波前调制能力，实现了与径向位置无关的均匀方位角剪切位移，显著提高了精度和稳定性。我们的方法消除了对笨重的光学元件和精确的多径对准的需求，使其对环境干扰更具弹性。它的多功能性通过在全光边缘检测、微分干涉对比显微镜和像差波前传感中的应用得到了证明。这些结果强调了它在实时模拟图像处理、先进光学成像和光学测试方面的潜力。
