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 broadband, compact, robust meta-optics-based azimuthal interferometer in common-path configuration, reducing the system size millimeter scale. Unlike designs, meta-optic utilizes localized modulation capabilities of meta-optics achieve uniform displacement independent radial position, significantly enhancing accuracy stability. Our approach eliminates need bulky optical components precise multipath alignment, making it more resilient environmental disturbances. Its multifunctionality demonstrated through applications all-optical edge detection, differential interference contrast microscopy, aberrated sensing. These results underscore its potential real-time analog image processing, advanced imaging, testing.
