ABSTRACT:
A pressure actuated optical relay containing a transparent mirror housing, located at the intersection of two optical paths. A liquid metal slug is moved within a channel passing through the transparent mirror housing by the action of pressure exerted by an actuation fluid. The liquid metal slug is moved in or out of the transparent mirror housing to select between the optical paths. When the liquid metal slug is within the optical path, an incoming optical signal is reflected from a reflective surface of the slug. The liquid metal of the slug adheres to wettable metal surfaces within the channel to provide a latching mechanism.
