Patent ID: 6903490

Claim:
A piezoelectric optical relay array of one or more array elements, wherein an array element of the one or more array elements comprises: a first input optical path; a first output optical path, optically aligned with the first input optical path to form a direct optical path; a second output optical path intersecting the first input optical path; a transparent mirror housing, located at the intersection of the first input optical path and the second output optical path; a liquid metal slug adapted to move within a channel passing through the transparent mirror housing, the liquid metal slug having a reflective surface; a first piezoelectric actuator operable to move the liquid metal slug within the channel so that it blocks the direct optical path and completes a reflected optical path from the first input optical path to the second output optical path; and a second piezoelectric actuator operable to move the liquid metal slug within the channel to remove it from the direct optical path.
