Tri-phasic emitter

A tri-phasic emitter was a weapons technology which allowed a vessel to simulate the weapons fire of alien spacecraft.

The Romulan drone-ship was equipped with tri-phasic emitters, as part of the Romulan plot to frame different alien species for attacking other ships. In 2154, it used the emitters to simulate Tellarite particle cannons, and utilized holographic projectors to disguise itself as a Tellarite cruiser while attacking the Andorian warship Kumari. The drone ship's emitters were later used to imitate Andorian weapons while attacking the, and to simulate Starfleet phase cannons while attacking a Rigelian scout ship.
