We have demonstrated that holograms incorporating changes in three-dimensional (3D) scenes can be recalculated in real time to present dynamic updates on information displays. This approach displays 3D information in a compatible format for fast and reliable interpretation of changes in the 3D scenes. The rapid-update algorithm has been demonstrated by real-time computation and transcription of the holograms to our digital micromirror device hologram projection system for visual validation of the reconstruction. The reported algorithm enables full parallax 1024×768 pixel holograms of 3D scenes to be updated at a rate of 0.8s with a 1.8GHz personal computer. Volumetric information displays that can enhance reliable data assimilation and decrease reaction times for applications such as air-traffic control, cockpit heads-up displays, mission crew stations, and undersea navigation can benefit from this research.
