First fiber optic bundles with polished ends are disposed within a wall thickness of the jacket and diffusers are attached to the polished ends at the control end. Second fiber optic bundles are disposed within the wall thickness of the jacket, interspersed with the first fiber optic bundles. Lenses are attached to selective first fiber optic bundle at the control end. A mechanism is positioned at the control end and coupled to the first and second blades.
