Asgard holography

The holographic technology of the Asgard is very highly advanced. It is able to send a holographic image of something to a place far away, even over many light years. When a hologram is activated, it gives a near real representation of the image similar to the holograms of Star Trek. These technologies are often incorporated into the Halls on their protected planets, and utilize them in communications with the High Council.

This device is often used to produce a holographic image of a person, which then is sent to the people with whom the person wants to talk. Holographic projections can also be used strategically, to distract enemy troops from battle without risk to the user. This technology was copied by Anubis from Thor's mind and used several times to contact Earth.
