Abstract
Information is derived from a selected fluorescent radiation line produced when an object is illuminated by a flying spot scanner. The illuminating radiation has an energy level sufficient to produce the fluorescent line when targeted components of the object are present and illuminated. A detector senses a fluorescent radiation line emitted from the targeted components to generate electrical fluorence based signals.
