  • Light beam detector
    Patent number: 6259103
    Abstract: Provided is a detector for an IR laser beam which has a chopper wheel of alternating spokes and spaces, the spokes having phosphor coatings thereon. The chopper wheel is placed in the path of the beam and rotated so the IR beam forms a visible or luminous spot on the rotating phosphor coats which are recharged. Intermittently, the IR beam passes through the rotating openings between the spokes to continue on its path to a mirror or target and the like. At the same time, as noted above, the beam forms a visible spot on the rotating phosphor coatings so as to depict the location, size and quality of the normally invisible IR beam.
