A method and a medium for laser imaging is herein disclosed. The medium incorporates one or more types of microstructures having a predetermined heat or radiation modifiable optical characteristic such as color, scattering, diffusion, diffraction, interference and iridescence. Associated intimately with the microstructures is a radiation antenna that acts to absorb radiation from a radiation source. The radiation antenna and source are attuned to one another to efficiently transfer energy therebetween and subsequently to the microstructures; this transfer of energy results in the modification of an optical characteristic of the microstructures to form an image on the medium. The medium has one or more layers that may include both the radiation antenna and the microstructures. Alternatively, the microstructures and radiation antenna may be included in separate layers. Coatings that incorporate one or more layers that include distinct microstructures and radiation antennae are also contemplated.
A method of forming an image on a medium comprising:
A medium for laser imaging comprising a substrate having a coating applied to a surface thereof, the coating comprising a radiation antenna adapted to absorb radiation within a predetermined range of wavelengths and a plurality of microstructures, the microstructures having a predetermined heat-modifiable optical characteristic.
A medium for laser imaging comprising a substrate having a first coating applied to a surface thereof, the coating comprising a radiation antenna adapted to absorb radiation within a predetermined range of wavelengths and a second coating that comprises a plurality of microstructures, the microstructures having a predetermined heat-modifiable optical characteristic, the second coating being at least partially transmissive with respect to light within the predetermined range of wavelengths.
A medium for laser imaging comprising a substrate having a coating applied to a surface thereof, the coating comprising a radiation antenna adapted to absorb energy within a predetermined range of wavelengths and a plurality of discrete microstructures disposed within the coating, the microstructures having a predetermined heat-modifiable optical characteristic.
A medium for laser imaging comprising a substrate having a coating applied to a surface thereof, the coating comprising a radiation antenna adapted to absorb radiation from light within a predetermined range of wavelengths and a plurality of discrete microstructures disposed on the coating, the microstructures having a predetermined heat-modifiable optical characteristic.
A medium for laser imaging comprising a substrate having a coating applied to a surface thereof, the coating comprising a radiation antenna adapted to absorb energy within a predetermined range of wavelengths and a curable polymer that is cured by the absorption of energy by the radiation antenna.
A medium for laser imaging comprising a substrate having a coating applied to a surface thereof, the coating comprising a curable polymer that is cured by the absorption of radiation within a predetermined range of wavelengths.
A printing mechanism for printing an image on a medium comprising:
A printing mechanism for printing an image on a medium that comprises a substrate having a coating applied to a surface thereof, the coating comprising a radiation antenna adapted to absorb radiation within a predetermined range of wavelengths and a plurality of microstructures, the microstructures having a predetermined heat-modifiable optical characteristic, the printing mechanism comprising:
