<p>A target apparatus for detecting laser radiation, or the like, impinging thereon. The target has a support (28) having a plurality of fiber optic fibers (27) mounted thereon with their ends attached to a radiation detector and amplifier (30). A radiation scattering cover (14, 31, 36) covers the fiber optic fibers on at least one side to scatter radiation impinging thereupon adjacent the fibers, thereby changing the angle of light entering the fibers to produce a signal on the detector to indicate a beam of radiation hitting the target. </p> |
