Abstract: These and other objects of the present disclosure can be achieved by provision of an apparatus for illuminating a structure(s), which can include a first arrangement and a second arrangement which can each be configured to rotate and deflect a radiation(s) transmitted therethrough at an angle with respect to an axis of rotation thereof. There can be a plurality of rotating third arrangements, where at least one can be connected to the first arrangement, and at least another one can be connected to the second arrangement. A fourth arrangement can be connected to the third arrangements, and can he configured to rotate the third arrangements. One of the rotating third arrangements can be flexible, can have a length that is greater than ten times a diameter of the first arrangement or the second arrangement, can he surrounded by a housing, and/or can contain an optical waveguide arrangement extending therethrough.
