Multiphasic emitter
Reed and Veylo bond over multiphasic emitters
A multiphasic emitter was a component of certain directed-energy weapons, including Starfleet phase cannons in the 22nd century.
Lieutenant Malcolm Reed, chief tactical officer of Enterprise NX-01, described these emitters to Veylo, the tactical officer from a Vissian starship, while giving her a tour of the armory. (ENT: "Cogenitor")
