Introduction to the hologram

International Journal for Research in Applied Science and Engineering Technology, 2021

In this paper we discuss about the current technology "Holographic Display/Projection" and its interactive feature. We discuss about the holograms, their types, physics and mathematics used in it, its interactive feature of responding to finger gestures and the hand-drawn interface (electro-holography). We also discuss about the applications of Holography and the future of this technology, how will it help and what can be the advancement, and also the hypothetical suggestions that what else new can be added further in this technology. And ends with a conclusion that what have we found out in the research, what is the scope of this technology, why this should be used, and where can it be used. We will also learn that how this technology can help the humans to become futuristic and advanced.

Invented in 1962, holography is a unique merging of art and technology. It persisted at the scientific cutting edge through the 1990s, when digital imaging emerged and supplanted film. Today, holography is experiencing new interest as analog holograms enter major museum collections as bona fide works of art. In this essay, we articulate our initial steps at Northwestern's Center for Scientific Studies in the Arts to describe the technological challenges on the conservation of holograms, emphasizing their nature as an active material. A holographic image requires user interaction to be viewed, and the materials are delicate and prone to deterioration. Specifically, we outline our methods for creating digital preservation copies of holographic artworks by documenting the wavefront of propagating light. In so doing, we demonstrate why it remains challenging to faithfully capture their high spatial resolution, the full parallax, and deep depths of field without terabytes of data. In...

Displayers tend to becomethree-dimensional.Themost advantage of holographic 3D displays is the possibility to observe 3Dimages without using glasses. The quality of created images by this method has surprised everyone. In this paper, the experimental steps of making a transmission hologram have been mentioned. In what follows, current advances of this science-art will be discussed. The aim of this paper is to study the recent improvements in creating three-dimensional images and videos by means of holographic techniques. In the last section we discuss the potentials of holography to be applied in future.

Practical Holography XIX: Materials and Applications, 2005

Holography and computer graphics are being used as tools to solve individual research, engineering, and presentation problems within several domains. Up until today, however, these tools have been applied separately. Our intention is to combine both technologies to create a powerful tool for science, industry and education. We are currently investigating the possibility of integrating computer generated graphics and holograms. This paper gives an overview over our latest results. It presents several applications of interaction techniques to graphically enhanced holograms and gives a first glance on a novel method that reconstructs depth from optical holograms. -weimar.de/medien/AR; www.holographics.de (high-resolution color versions of images presented in this paper are available online)

Holography - Basic Principles and Contemporary Applications, 2013

This paper focuses on digital holography. The techniques for producing holograms based on a computer-generated content are outlined, focusing on different approaches and technologies. The extended capabilities of using digital holograms for a variety of applications are also outlined in a detailed way. In addition the way of creating digital-content for a hologram is described based on t he experience of generating this content by us. Difficulties and different techniques will be discussed.
