Method for enhancing the resolution of holographic displays

Shakeeb Bin Hasan, Tomasz Kozacki


We present an investigation into the resolution limit and its enhancement for holographic display systems implemented by a liquid crystal on silicon spatial light modulators (SLMs). The problem of resolution of the displayed objects is connected with a limited pixel pitch of the spatial light modulator. Furthermore, it delimits the angular view-ability of reconstructed objects, which is the most important factor influencing the applicability of display systems. In this regard, we will present a solution using multiple SLMs set to work together. Such a configuration allows us to ease the resolution limit which in turn provides larger angular view-ability. A theoretical analysis based on a plane wave spectrum is presented, followed by numerical simulations, to demonstrate the utility of the concept.
