Abstract
A high-performance ultraviolet excitation source is made with one or more ultraviolet-emitting LED's or ultraviolet-emitting laser diodes, which may be modulated at various frequencies for strobing or synchronous detection. The source may optionally include one or more visible-light LED's, such as white-light LED's, for detection of visual features of an article under examination. Methods and apparatus using the ultraviolet source for authentication, quality control, and sports or entertainment are described.
