Optical metasurfaces (MSs), with their inherent design flexibility and subwavelength-scale control of light, offer promising solutions for miniaturizing bulky optical components. Shared-aperture MSs further enhance functionality by integrating multiple through segmented or interleaved designs. However, under uniform illumination, all encoded functions are simultaneously activated, resulting in undesirable crosstalk enhanced background. In this work, we propose experimentally demonstrate selectively addressed (ILMSs) making use the dynamically controlled Talbot effect, which is realized a configuration comprising diffraction grating (DG) cascaded piezo-controlled polarization-multiplexed ILMS. By accurately controlling DG-ILMS distance, leverage position-dependent fringes to achieve dynamic activation different functionalities. We believe that our approach provides versatile integrated solution addressing multifunctional ILMSs thereby paves way development advanced highly systems.
