Photonic crystal security device |
| abstract |
An optically variable security device comprises a photonic crystal fo which incident light received by the crystal is selectively reflected o transmitted by the crystal to generate a first optically variable effec observable over a first set of directions. Incident light received by the crystal is also selectively reflected or transmitted by the crystal to generate an optical effect observable over a second set of directions that is different from the first set. |
