Ans: Photography, microscopy, image retrieval, and image replication are examples of optical image creation applications. The effects of acoustic, x-ray, electron beam and microwave holography are discussed briefly. Contour generation and interferometry are the second main application field. To put the current operation in context, the applications are addressed with some historical background. Finally, the basic types of holograms, as well as their properties, are defined.China 3D Hologram Fan Wall
