Abstract
The present invention is directed to a monitor system that measures flight characteristics of at least one object moving in a predetermined field-of-view using at least one fluorescent marker. In one embodiment, the emission spectra of the fluorescent marker is preferably narrow and substantially symmetric. It may be desirable for the fluorescent marker to be capable of responding to a broad excitation spectra. Preferably, the fluorescent markers comprise quantum dots. The quantum dots may be manufactured in any desired manner, and may comprise semiconductors, gold atoms, and the like.
