This document discusses 3D holographic projection technology. It provides an introduction to 3D holography, covering its history from Dennis Gabor's discovery in 1947 to advances enabled by lasers in the 1960s. The document outlines the working principles of 3D holographic projection using interference between light sources to create the illusion of three-dimensional imagery. Advantages include enabling glasses-free 3D viewing of virtual objects, while disadvantages include higher production costs compared to 2D. Applications discussed include entertainment, education, and medical imaging. The document concludes that holographic displays will increasingly replace other displays and enable new applications as the technology advances further.
Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics.

This seminar examines the new technology of Holographic Projections. It
highlights the importance and need of this technology and how it represents the new
wave in the future of technology and communications, the different application of the
technology, the fields of life it will dramatically affect including business, education,
telecommunication and healthcare. The paper also discusses the future of holographic
technology and how it will prevail in the coming years highlighting how it will also
affect and reshape many other fields of life, technologies and businesses.
Holography is a diffraction-based coherent imaging technique in which a
complex three-dimensional object can be reproduced from a flat, two-dimensional
screen with a complex transparency representing amp litude and phase values. It is
commonly agreed that real-time holography is the ne plus ultra art and science of
visualizing fast temporally changing 3-D scenes. The integration of the real-time or
electro-holographic principle into display technology is o ne of the most promising but
also challenging developments for the future consumer display and TV market. Only
holography allows the reconstruction of natural-looking 3-D scenes, and therefore
provides observers with a completely comfortable viewing experience. But to date
several challenges have prevented the technology from becoming commercialized. But
those obstacles are now starting to be overcome. Recently, we have developed a novel
approach to real-time display holography by combining an overlapping sub-hologram
technique with a tracked viewing-window technology.
We can often see three–dimensional holographic communication technology in science fiction movies, using the principle of three-dimensional computer graphics, and the distant person or thing can be projected in the air in the form of a three dimensional. With the development of science, all the equipment miniaturization and precision, the display device cannot match and humans would increasingly demand a new display technology to solve the problem. The 3d holographic projection precisely fits this role.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. INTRODUCTION TO 3D HOLOGRAPHY
• Holography is composed of the Greek terms, "holos" for "whole
view" and “gram” for "writing or drawing“
• Technical term for holography is wave front reconstruction
• Image changes as the position and orientation of the viewing
system changes
• Records phase of the object
• Record our three dimensional world on a
two dimensional recording medium
4. HISTORY OF 3D HOLOGRAPHY
• Dennis Gabor - discovered the basic technology
of holography in 1947
• Optical holography did not really advance until
the development of the laser in 1960
• First practical optical holograms that recorded
3D objects to be made in 1962
• Yuri Denisyuk from Soviet Union
• Emmett Leith and Juris Upatnicks from USA
• Advanced notably since the 1980s owing to low-cost
solid-state lasers
Dennis Gabor (1900-1979)
6. IMPORTANCE AND NEED OF
3D HOLOGRAPHIC PROJECTION
• Project large-scale, high-resolution images onto free space
• Accommodate multiple viewers independently and
simultaneously
• Create tremendous effects on all fields of life including
business, education, science, art and healthcare
• Enabling viewing and manipulation of virtual 3D objects in 3D
space without the need for special viewing goggles or headgear
8. Holography is a
two-step
process.
First step is the
recording of
hologram where
the object is
transformed
into a
photographic
record.
The second step
is the
reconstruction
in which the
hologram is
transformed
into the image.
PRINCIPLE
9. WORKING OF 3D HOLOGRAPHIC
PROJECTION
• The way 3DHT operates is by creating the illusion of
three-dimensional imagery.
•A light source is projected onto the surface of an object
and scattered.
• A second light illuminates the object to create
interference between both sources.
•Essentially, the two light sources interact with each
other and cause diffraction, which appears as a 3D
image.
15. WORKING OF 3D HOLOGRAPHIC
PROJECTION
• It starts with the patented
foil, completely invisible to
the naked eye, right at 45°
across the stage.
• Also known as ''Mission
Eyeliner'‘.
• Loosely based on an
illusionary technique called
Peppers Ghost.

18. WHAT WE COMPUTER ENGINEERS
CAN DO IN THIS HOLOGRAPHY?
• Can describe all of the interactions between the object and
reference beams, as well as the shapes of the interference
fringes, using mathematical equations
• Makes it possible to program a computer to print a pattern
onto a holographic plate, creating a hologram of an object
that doesn’t actually exist
20. ADVANTAGES OF 3D HOLOGRAPHIC
PROJECTION
• A high resolution three dimensional images
• Glasses free 3D display
• No need for projection screen
• Life like images
• Interactive display
•Planning & simulation
21. DISADVANTAGES OF 3D
HOLOGRAPHIC PROJECTION
•Production cost is much higher that 2D
•Not easily see under Florescent Lighting
•Application to products is costly
•Time consuming when it comes to constructing images
22. APPLICATIONS OF 3D HOLOGRAPHIC
