Patent ID: 7351061

Claim:
A pattern testing board for detecting an emission beam's presence and projected beam pattern, said pattern testing board comprising: (a) a single emission beam having a projected beam pattern formed by an intersection of said emission beam and a target surface; (b) a plurality of emission beam sensors responsive to at least a portion of said projected beam pattern, said projected beam pattern being larger than a single emission beam sensor; (c) a plurality of hit indicators each in communication with and responsive to at least one emission beam sensor, each hit indicator substantially adjacent its associated said emission beam sensor; (d) each said hit indicator adapted for signaling the sensing of at least a portion of said projected beam pattern by said emission beam sensor; and (e) together said plurality of hit indicators signaling any sensed at least a portion of said projected beam pattern and providing a graphic, visual representation of said any sensed at least a portion of said projected beam pattern.
