  • Patent number: 9658022
    Abstract: Optical sensing of trigger region incursion in the context of a firearm training system may be enhanced or otherwise improved through selective use of light absorbent materials within an optical detection range of one or more optical sensors. Surfaces located within a field of view of the optical sensor(s), such as interior facing surfaces of the trigger guard, surfaces of the trigger, and other surfaces located along the optical signal path may include light absorbent materials, such as dark surface colors, matte finishes, surface textures, and/or thin-film coatings that filter and/or absorb light of a particular wavelength or wavelength range.
