Holographic MemoryABSTRACT: Holography is a technique which allows recording and playback of 3- dimensional
image. The is called a hologram unlike other 3-dimensional “picture” hologram provide hologram provide what is called “parallax”. Parallax allows the viewer to move back and forth up and down and see different perspective – as if the object were actually.
In Holography, the aim is to record complete wave field (both amplitude and phase) as it is intercepted by recording medium the record in plane may not even be an image plane. The scattered or reflected light by object is intercepted by the recording medium and recorded
completely in spite of the fact that the detector is insensitive to the phase difference among the various part of the optical field In holography, interference between the object wave and
reference wave is formed and recorded on a holographic material. The record known as
hologram (whole record) captures the complete wave which can be viewed at the later time by illuminating the hologram with an appropriate light beam.
To this day holography continues to provide the most accurate depiction of 3-D image in the world.
