Systems and methods disclosed herein include an optical barrier structure, which may include: a frame defining an aperture; first and second elongated structural members, each elongated structural member including first and second ends, such that the first and second elongated structural members can be connected at their first ends to opposite sides of the aperture, and further such that the first and second elongated structural members can extend from the frame parallel to and in the same direction as each other; and an optically opaque barrier member positioned to extend between respective second ends of the first and second barrier members.)
