Produced in multiple ways:<ul><li style="font-weight:400;">Reflective Screens</li> <li style="font-weight:400;">Projections onto fog</li> <li style="font-weight:400;">Then you have the classic “Pepper’s Ghost” illusion. Started in the 1860s<ul><li style="font-weight:400;">A brightly lit figure out of the audience's sight below the stage is reflected in a pane of glass placed between the performer and the audience. To the audience, it appears as if the ghost is on stage.</li> </ul> </li> </ul> </li> <li style="font-weight:400;">Old ways are low in resolution, while the new system, from Cambridge and Disney, is designed to boost the picture quality with scalable, modular holographic blocks, or holobricks as the team calls them.<ul><li style="font-weight:400;">Each holobrick is made up of a spatial light modulator, a scanner, and coarse integrated optics.</li> </ul> </li> <li style="font-weight:400;">The system combines three images of the same object from slightly different angles, which creates a sense of depth.<ul><li style="font-weight:400;">Then light is then sent through a series of lenses that separates the images, so that when it appears on the 2D display on the surface of the holobrick, but from different angles.</li> <li style="font-weight:400;">Has a resolution of 1024 x 768, a 40-degree field of view and at a cinematic frame rate of 24 frames per second.</li> </ul> </li> <li sty
