Applications of Computational Holographic Imaging(CHI)

           Applications of Computational Holographic Imaging


While  going  through some quotes on the internet , I came across one quote  which I would like to share with you all ...
           “Life is a hologram. Even the smallest moment contains eternity within it.”
                                                                                                       -Banani Ray 
 This relates the concept of hologram to our life in very philosophical way...like this there are many applications of holograms in industrial sector and our life
As we know that the holography uses the concept of interference, we can have many applications  of it in the different sectors .since holography is a two-stage process of photography using  light from a laser  where,in the first stage a hologram is formed by combining the light scattered from the object and the direct laser beam on a photographic plate and then three- dimensional image is reconstructed by directing the laser beam through the hologram.         The total process used in above paragraph can result in many applications such as information storage, image recording in depth, the use of holograms as optical elements, precise interferometric measurements on three-dimensional objects. Now-a-days there are many uses of holography  in scientific research, engineering and medical assessment.

  • To prepare the samples in medical assessment and to view the images of the specimans clearly, X-ray holography is used widely where X-ray holography is a type of coherent diffractive imaging where the phase information is encoded in the diffraction pattern by means of interference with a reference beam and the image of the specimen is obtained by a single Fourier transform of the interference pattern.

  • For non destructive imaging without contact with high resolution inside cavities of internal organs, Endoscopic holography is used. Endoscopic holography combines the concepts from holography and endoscopy.Endoscopic holography has ability to  record 3-D large focal depth and high resolution images of tissues.
             
  • Holographic stereogram,conical stereogram and multiplex hologram are used to synthesize the three dimensional  images of biological specimans. Multiplex holography uses the scaled images of the objects making the hologram.
  • Holograms provide way to store the toothprints in dentistry where tooth prints are the records for forensic purpose.
  • Holographic contouring technique is used to study the topography of teeth.
  • In semiconductor industry electron holography is used to create images from materials at atomic dimensions and study changes in fields of nanostructured materials, DRAM capacitor design and high temperature superconductors.

         So we can have more applications like above in future which may help us in  field of education,IT industry etc. Really holographic imaging has simplified our life to the great extent.
                                                                                  
                                                               Thank you!!

Raster graphic model in holography

By
Raster graphic models are the most common and better suits to an object data provided by physical extra sensors, such as image and 3D scanner.  In computer graphics , a  raster matrix  is a dot matrix which is a data structure  that represents a  rectangular  grid of pixels   , viewable on a monitor , paper , or other displays. These rater graphics are digital images created as a set of samples of a given space .It has a raster grid of x,y and z coordinates for 3D images.The image file decides which of these coordinates to illuminate in monochrome or color values.It is also referred to as bitmap because it contains information that is directly mapped to the display grid. Raster graphics model in 3D is composed of tiny squares that work together to create a recognizable object hologram:- The image below shows greyscale raster graphic model implemented by hologram display:- Images source:- https://images.wisegeek.co...

Computational Holographic Imaging for 3D Holographic Projection

By
In this blog,we will see how amazingly we can use the computer hologram images for three dimensional projection.As we have seen in earlier post that the 3D hologram can be seen without using 3D glasses.So,How do they do it? The concept is actually based on an illusionary technique called Peppers Ghost .John Henry Pepper was the one who attempted to popularize this effect.It was first used in Victorian Theaters   across   London in the 1860s. In pepper's ghost there are two rooms, one room is visible to the audience which is the "main room  and the other one is hidden called as "blue room". A plate of glass is placed somewhere in the main room at an angle that reflects the view of the blue room towards the audience. Generally this is arranged with the blue room to one side of the stage, and the plate on the stage rotated around its vertical axis at 45 degrees. This can be used to make objects appear to float in space. Isn't it interesting? ...

Background

By
    image source:iStock The concept of hologram/holography originated in Hungary when one of the resident scientists there invented it as a method to improve the resolution of electron microscopes .         Holography is composed of following main processes:         1. Calculations for   the scattered wavefronts originating from the object.         2. Encoding the data for display purpose.         3. Visual reconstruction from   the interference pattern onto a coherent beam of light by using some technologies and transport it to the user  who is going to observe the hologram.         Now that we're done with a brief intro to this topic we shall be looking further deep into what goes inside to develop such fascinating or 'real life-like'  technology. Do visit our next blog for more such information!
