  • Optically detectable marker including luminescent dopants and system and method for reading such markers
    Patent number: 11043058
    Abstract: An optically detectable marker having a matrix material, which is doped with individual luminescent dopants, including a first luminescent dopant and a second luminescent dopant. The first luminescent dopant includes a first unique absorption band such that the first dopant may be excited by illumination of a first wavelength. The first dopant is distributed in the matrix material so as to form a first spatial pattern in the matrix material, which pattern may be optically detected by illuminating the marker by a light source illuminating light of the first wavelength. The second luminescent dopant includes a second unique absorption band such that the second dopant may be excited by illumination of a second wavelength, different from the first. The second dopant is distributed in the matrix material so as to form a second spatial pattern in the matrix material, which pattern may be optically detected by illuminating the marker by a light source illuminating light of the second wavelength.
