Holotrap

Holotraps are devices for capturing rogue holograms. They project a beam of energy upwards when in operation and store the hologram inside until it can be released back into the simulation it escaped from.

Fiction

Rescue Bots Academy

After accidentally letting a rabbit escape from Hero Hall, Hoist and Hot Shot used a holotrap to recapture it. Unfortunately during their absence, a herd of cows escaped from the sim, requiring them to use the holotrap to round them up before anyone else noticed. One Of Our Dragons Is Missing

Notes

• Holotraps may be an adaptation of the technology from Doc Greene's Spectral Vapor Filter, which turned out to be effective at trapping holograms.
• They're probably unrelated to ghost traps, however.
