What is a Hologram

16 04 2007

Hologram is a high-tech optical laser-recording of visually a 3D image bearing the multi layer impressions of the customised artwork with various security features — demonstrating multiple images reconstructed as one image having complete parallax & depth-of-field (due to high refraction of light) floating in space behind and/or in front of the 2D recording medium.
Different cross-sections of the image can be seen along different directions when viewed at the correct angle of light.
Its dramatic effects looks “real” because of vibrant colours, motion, and images at different depths
