  • Using of enhanced retroreflectors for non-visible light
    Patent number: 8686371
    Abstract: This is a way interrogating an object using retro-reflection of non-visible light. It uses e.g. IR transmitted toward the object from a distance and covertly detects the retro-reflection. Highly reflective passive non-visible light retroreflectors on the object reflects and refracts light back toward the light transmitter, with the returned light being very nearly parallel to the light from a narrow beam light transmitter.

  • Method of coating a retroreflector to avoid reflecting visible light
    Patent number: 8585222
    Abstract: This describes an enhanced retro-reflector that is designed to be a retro-reflector of non-visible light, but not visible, and can be designed to resemble common dust or dirt in the visible spectra. As the beads retro-reflect very little visible light they are not easily seen in visible light; thus they are difficult to counterfeit.
