Hologram denotes to be a physical structure which diffracts light into the image and it refers to the encoded material and the resulting image. The holographic image can be seen in holographic print or through the laser by which the image gets projected in the screen.
Understanding its principles along with its inference a hologram records the difference between the two beams of the coherent light. The composed light will travel on all directions and at equal length. The laser beam gets split into two parts where it called reference beam which strikes to the photographic plate and the other second one strikes and bounces on the plate. This phase interference displays image in three dimensional with the help of the coherent light.
Understanding the Types:
It gets categorized into 2 types which are the Transmission hologram that captures image by transmitting beam of light through it. The laser is the light source which emits and hits the beam splitter into the object beam and the reference beam.
The reflection hologram captures the image by reflecting a beam of light. The reference beam light reflects off a mirror and shines on the photographic plate. The object beam and reference beam meets at the photographic plate and create the interference pattern that records the resulting wave.
Holography: Current and Future Applications
Holography technology stands to be a platform for the innovations in many areas such as medicine, scientific research and other industries.
Some Current Applications:
Holographic interferometry is used by researchers and industry designers to test and design many things example tires and engines, artificial bones and joints.
- Supermarket and department store scanners use a holographic lens system
- Holographic Optical Elements are used for navigation by airplane pilots.
- Medical doctors can use three-dimensional holographic CAT scans to make measurements.
- Holography are used in advertisements.
Future applications of holography include:
Many researchers believe that holographic televisions will become available within 10 years. Holographic memory is a new optical storage method that can store 1 terabyte of data in a crystal approximately.
The technology that bring the imagination to being, the reality that makes a difference and proves to be the future of tech-world.
