Method for enhancing the resolution of holographic displays

Shakeeb Bin Hasan, Tomasz Kozacki

Abstract


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.
