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. The system may include a lighting unit with a light filter, at least one camera unit with a camera filter. The lighting unit directs light in the direction of the object. If there is a light filter the light is filtered prior to reaching the object. The camera unit is pointed toward the object and the camera filter inhibits all wavelengths except those in a certain range. The reflected light from the object is transmitted to the camera through the camera filter. In one embodiment, the system includes a camera filter that is electronically switchable between at least two colors. The present invention further includes methods for monitoring at least one object with at least one marker using filters.

28. A method of measuring the kinematics of at least one object comprising:
-
providing a first object having at least one fluorescent marker thereon;
directing a first light towards a field-of-view comprising the first object, wherein the first light contacts the at least one fluorescent marker and is reflected as a second light to a light receiving unit, and wherein the second light comprises an image of the first object;
recording the image of the first object; and
analyzing the recorded image of the first object for a first bright area, wherein the first bright area corresponds to the at least one fluorescent marker.
