Holograms: Advantages and Disadvantages

Holograms are an advanced technology that can recreate 3D objects in midair. One can find information about holograms by just entering the key word: holograms in the search box of any browsers. Advantages and Disadvantages are listed below.

Advantages:
  • Cost effective
  • Higher storage capacity
  • Increased feasibility of objects (depth)
  • Enables the achievement of multiple images on a single plate and 3D images
  • Ability to combine with other technologies
Disadvantages:
  • Provide static images
  • Do not produce images of complex movement
  • Require complicated precise machinery to produce and view an image
  • Low axial resolution of inline holography
  • Reference illumination beams are collinear
