Early emitters had difficulty operating in non-atmospheric conditions such as space or decompressed airlocks. To work around this issue, engineers adopted a “magnetic cage” to trap an adequate density of matter from which a screen could be created. The “cage” was formed by directional magnetic fields which prevented the screen’s dissipation into the vacuum of space.
Hologram emitters are based on reliable, if antiquated, technologies developed in the first quarter of the 21st century. The emitters allowed digital information to be visualized and projected onto a three dimensional “screen” of localized, compressed atmospheric elements. Controlled electromagnetic bursts would then be applied to the screen, allowing the excited atoms to give off the appropriate light waves, ultimately resulting in a full three dimensional image composite.
