Abstract
A firing apparatus includes a light generating device for emitting a modulated light beam that includes information regarding the firing apparatus upon triggering in a direction toward a target. Lens optics is positioned in a path of the modulated light beam including a one dimensional lens for beam shaping the modulated light beam to provide a shaped modulated beam including a low divergence horizontal beam portion and a vertically elongated beam portion. A combat training system includes a head mounted apparatus including at least one photodetector affixed. The vertically elongated beam portion allows the light beam generated by the firing apparatus to be aimed at the torso of the target and be detected by photodetectors that are exclusively on the helmet.
