| description | This paper is to describe a color digital holographic projector and this system is comprised of RGB lasers, 3 units of Digital Micro-Mirror Device (DMD) and high speed rotating diffuser. In this research, we focused on colorings Digital holograms and synchronized RGB digital holograms versus rotated diffuser. To achieve this phenomenon, three of the holograms optical path need to be aligned to pass through a same beam splitter and eventually combined as one colored holograms output While, this colored hologram will be reconstructed on volumetric screen (rotated diffuser) at the floating manner in free space. To obtain these result 3 key factors is investigated: 1. To configured 1 master and 2 slaves digital micro mirror illumination time 2. To reconstructed holograms orientation angle diffuser versus rotating speed. 3. To synchronize rotating diffuser speed versus DMD frame-rate Last but not least, the team built a prototype Color Digital Holography Display but more developments are required to follow up such as, enhance system's reliability, robustness, compactness and 3D realistic images floating in the free air space. |
