Tri-phasic emitter
A tri-phasic emitter was a piece of Romulan technology that simulated 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 , and to simulate Starfleet phase cannons while attacking a Rigellian scoutship. ()
