- Abstract
- Light emitting diode (LED) has been a prominent component for illumination source of holographic displays. It can replace laser in that it alleviates speckle noise in reconstructed hologram and is regarded as a safer source. However, LED-based holographic displays can reconstruct an image in a limited depth range due to partially coherent characteristic of LED itself. In this paper, we propose a prototype of LED-based holographic near-eye display with focus tunable lens to expand the depth range. The feasibility of the system is supported by several experimental results.
