Abstract
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.
