Abstract
A system comprises at least one optical fiber that revolves around an axis when an array assembly that includes a radar array revolves around the axis. The optical fiber receives a light pattern that specifies information from the array assembly. A stationary device remains optically coupled to the optical fiber for receiving the light pattern while the optical fiber revolves around the axis.

27. A method for conducting light, comprising the steps of:
-
revolving a radially oriented optical fiber around the conical reflector;
directing a light beam through a first optical path towards an apex of a conical reflector;
re-directing at least a portion of the light beam using the conical reflector;
transmitting the re-directed portion of the light beam through a second optical path perpendicular to the first optical path, wherein the second optical path begins at a side surface of the conical reflector and has a 360 degree field of view; and
transmitting the re-directed portion of the light beam from the second optical path to an input of the movable optical fiber while the movable optical fiber is revolving. - View Dependent Claims (28)
