Hologram Technology and History
Holographic security elements consist of nanostructures that refract light in a very specific manner. They enable 3D effects to be seen on what appears to be a flat surface. These structures can be originated by means of classical (analog) holography, where — comparable to classical photography — a photosensitive material is used for recording light. Similarly, a hologram is created by recording the interference patterns created by light waves. To form such patterns, two wavefronts must interfere, which is only possible if the wavefronts are coherent. To guarantee coherence for a specific length, the beam of a single laser is split into two coherent beams. To record a hologram, a system with various optical elements must be set up in a carefully measured manner under specific laboratory conditions: particle-free with high stability (no vibration) and consistent air temperature2.We do Master Plate Shooting In House.
