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.

Conclusion
Holography (from the Greek, whole + write) is the science of producing holograms.
It is an advanced form of photography that allows an image to be recorded in three dimensions.It involves the use of a laser, interference, and diffraction, light intensity recording and suitable illumination of the recording.

3D Holography: When Might it become Economically Feasible?Jeffrey Funk
Master's students use concepts from my (Jeff Funk) forthcoming book (Origins of New Industries) to analyze the technical and economic feasibility of 3D Holography. Improvements in lasers and holographic media are gradually making this more feasible. See my other slides for details on concepts, methodology, and other new industries..
holography is a method of producing a visual three-dimensions (3-D) image of an object by means of light wave patterns recorded on a photographic plate
PPT on 3D Holographic Projection Technology ( Hologram)SafwanSadi
A PowerPoint presentation consideration of the topic 3D Holographic projection Technology-based on interference fringes recorded on the Holographic plate. The Holographic projection Technology is a versatile topic for engineering or any graduate to be considered or study deep about can explore endless opportunities upcoming in the field of Holographic research or hologram.
A hologram is a three-dimensional image formed by the interference of light beams from a laser or other coherent light source. For videos, visit http://fractal.ae/holograms/
A hologram is a physical recording of an interference pattern which uses diffraction to reproduce a three-dimensional light field, resulting in an image which retains the depth, parallax, and other properties of the original scene.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. What is Holography?
Holography is a technique which enables three-
dimensional images to be made.
It involves the use of a laser, interference, diffraction,
light intensity recording and suitable illumination of the
recording.
The image changes as the position and orientation of the
viewing system changes in exactly the same way as if the
object were still present, thus making the image appear three-
dimensional.
3. Holography or ‘Lens less photography’
Holography is a technique that enables a light field, which is generally the product of
a light source scattered off objects, to be recorded and later reconstructed when the
original light field is no longer present, due to the absence of the original objects.
There are two physical phenomena as the principles of the holography: interference
and diffraction of light waves.
When the two laser beams reach the recording medium, their light waves intersect
and interfere with each other. It is this interference pattern that is imprinted on the
recording medium. The pattern itself is seemingly random, as it represents the way in
which the scene's light interfered with the original light source — but not the original
light source itself. The interference pattern can be considered an encoded version of
the scene, requiring a particular key — the original light source — in order to view its
contents.
11. Current Applications
Holographic interferometry is used by researchers and industry designers to
test and design many things, from tires and engines to prosthetic limbs and
artificial bones and joints.
Supermarket and department store scanners use a holographic lens system
that directs laser light onto the bar codes of the merchandise.
Holographic optical elements (HOE’s) are used for navigation by airplane
pilots. A holographic image of the cockpit instruments appears to float in
front of the windshield. This allows the pilot to keep his eyes on the runway
or the sky while reading the instruments. This feature is available on some
models of automobiles.
12. Holograms are used in advertisements
and consumer packaging of products to
attract potential buyers.
The use of holograms on credit cards and
debit cards provide added security to
minimize counterfeiting..
Sony Electronics uses holographic
technology in their digital cameras. A
holographic crystal is used to allow the
camera to detect the edge of the subject
and differentiate between it and the
background. As a result, the camera is
able to focus accurately in dark
conditions.
13. Future Application
Future colour liquid crystal displays (LCD’s) will be brighter and
whiter as a result of holographic technology. Scientists at Polaroid
Corp. have developed a holographic reflector that will reflect ambient
light to produce a whiter background.
Holographic night vision goggles.
Holographic memory is a new optical storage method that can store 1
terabyte (= 1000 GB) of data in a crystal approximately the size of a
sugar cube. In comparison, current methods of storage include CD’s
that hold 650 to 700 MB, DVD’s that store 4.7 GB, and computer hard
drives that hold up to 120 GB.
Optical computers will be capable of delivering trillions of bits of
information faster than the latest computers.
14. Future of holography
Holography is a very useful
tool in architecture.
Use of holography in
architecture is recording of
models and previsualise
new buildings.
It can provide attractive
method to traditional
methods in sales and
presentation.
15. Advanced
laser, optics, image
processing are incorporated
into Zebra 3D imaging to
produce Holography images.
This holography is possible to
create large city maps, full
seized cars, humans, and
machines
