What is Holography? | Take The RedPill!
By using multiple colour lasers a full colour Denisyuk reflection hologram can be recorded and is almost indistinguishable from the original object. The tendency on encountering such an image is to check its authenticity – to look behind the plate for the object. -- A hologram is a physical structure that diffracts light into an image. The term ‘hologram’ can refer to both the encoded material and the resulting image. A holographic image can be seen by looking into an illuminated holographic print or by shining a laser through a hologram and projecting the image onto a screen.
