<p>A luminescent fiber marker (14) and method comprised of a linear coaxial lens having an elongated thin cylindrical phosphorescent layer (10) and a pair of colinear and coaxial optical waveguides (11, 12) sandwiching the thin cylindrical phosphorescent layer (10) therebetween so that light (13) impinging on said cylindrical phosphorescent layer (10) along the length thereof is induced to store said radiation energy in said light and emit radiation (8) of a different wave length from the light (13) impinging on said cylindrical phosphorescent layer (10) into both of said optical waveguides (11, 12). Each of said optical waveguides (11, 12) has a fluorescent material (30, 40, 50) dispersed therein for absorbing the emitted radiation (8) from said phosphorescent layer (10) reemitting the absorbed radiation to effect an internal scatter of radiation in each of said waveguides (11, 12) to permit trapping within the waveguide cores. At least one of the ends of the pair of colinear and coaxial waveguides (11,12) is adapted to emit said light (8) of a different wave length, the ends may be arranged in various patterns and/or have diffuser (18) or mirrors (19, 20) associated therewith.</p> |
