Demonstrates enhanced phase modulation range using dual-panel liquid crystal technology, highlighting significance in holography.
In this paper, we propose a dual‐panel configuration utilizing commercial in‐plane switching (IPS) liquid crystal panels for holographic complex modulation. Phase modulation is achieved through symmetrically‐stacked IPS panels, using geometric phase shift to expand modulation range beyond conventional dynamic phase methods. Our demonstration includes a look‐up table that maps grayscale inputs to geometric phase shifts. Experimental results verify expansion of phase modulation range using this dual‐panel system.
