Abstract
In this paper, we analyze the image quality reconstructed by holographic display depending on spatial coherency and temporal coherency of the light source in holographic display system. The simulation was conducted by changing both spatial coherency and temporal coherency independently using proper modeling of coherency. A holographic display setup was composed to verify simulation results. LED and LD were respectively used as a light source for holographic display, and the quality of reconstructed images reproduced by using LED or LD was compared. The scheme of near-eye holographic display adopting LED as a light source which generates low speckle noise but narrow depth range was proposed. The proposed scheme of near-eye holographic display system was verified experimentally.
