<\/p>\nHologram is a 3D imaging technology that allows displaying realistic 3D images.
\nIn contrast to traditional 2D images that reflected light in the form of flat plates, holograms create images using optical interference.
\nA hologram is displayed as a realistic 3D image on a flat surface.
\nBut when you look at it, it seems like the image is in space and you can see it from different angles.
\nThis is because holograms retain and display depth information in the image.
\nBut the modern hologram is a combination of holographic technology and more advanced technologies that display three-dimensional images in a newer and more realistic way.
\nOne example of a modern hologram is a digital hologram that digitally creates three-dimensional images.
\nAnother example of a modern hologram is the quantum dot hologram.
\nModern holograms are also used in various industries such as advertising industries, exhibitions, etc.<\/p>\n
The process of producing a hologram by computer generally includes several steps.
\nThe main steps to produce digital holograms by computer are:<\/p>\n
At this stage, a 3D model of the desired object must be created first.
\nThis 3D model can be created by 3D modeling software such as AutoCAD, Blender or 3ds Max.
\nYou can also use 3D scanning to digitally recreate an object.<\/p>\n
<\/p>\n
In this step, the 3D model is divided into virtual surfaces.
\nEach surface is a combination of three-dimensional points defined by certain characteristics such as height and angle.<\/p>\n
For each surface, the Fresnel value is calculated.
\nFresnel is an optical interference pattern used to produce holograms.
\nTo calculate Fresnel, it is necessary to use mathematical functions and related formulas.<\/p>\n
To create more realism in the hologram, the Fresnels are randomly changed.
\nFor each surface, you can generate several samples of different fresnels and combine them.<\/p>\n
In this step, using the produced Fresnels and using optical interference methods, the optical interference between the Fresnels is calculated.
\nThis optical interference creates a three-dimensional image in the hologram.<\/p>\n

<\/p>\n
At this stage, the resulting 3D image can be digitally displayed.
\nThe devices display a three-dimensional image with the help of computer-generated optical interference patterns.<\/p>\n
In general, the process of producing a hologram by computer requires a combination of 3D modeling, optical analysis and image processing capabilities.
\nThis process is done by different softwares that support holography.<\/p>\n
Hologram engraving is a complex process that requires special equipment and expertise.
\nHere are some basic steps to engrave a hologram:<\/p>\n
Preparation of holographic matrix
\nIn this step, a holographic matrix is \u200b\u200bcreated that includes optical interference patterns.
\nThis matrix usually consists of a white or silver glass plate on which different patterns are created using lighting and embossing techniques.<\/p>\n
Preparation of hologram film
\nIn this step, using light-sensitive film (holographic film), the hologram image is engraved on the film.
\nHologram film is usually composed of layers of different materials capable of recording optical interference patterns.
\nHologram film is produced using special chemical processes.
\nProcessing and reconstruction
\nAfter engraving the image on the hologram film, it is necessary to reconstruct the image correctly.
\nFor this, the hologram film is read by a laser to interpret the light interference patterns in the film and produce the corresponding 3D image.
\nThis process is done using laser technology and optical signal processing.<\/p>\n
Since hologram engraving is a specialized process and requires equipment and technical expertise, it is often performed by companies and specialists in the field of holography.
\nThese companies and specialties usually have the ability to produce and engrave custom holograms and are suitable for use in advertising, as security labels on product packaging and other applications.
\nTo create your own holograms, you can visit specialized companies and make your request.<\/p>\n

Holographic wires are a new technology used to create holographic images.
\nThese wires include a fine and thin wire that, using nanophotonics and optical interference techniques, has the ability to record optical interference patterns and reconstruct 3D images.
\nIn holographic wires, special materials such as semiconductor materials, polymers and holographic materials are used.
\nThese materials have special optical properties that allow them to record and reconstruct optical interference.
\nOptical interference patterns are recorded on the holographic wire and reproduced in 3D using lasers and reconstruction techniques.
\nOne of the applications of holographic wires is in the field of 3D displays.
\nUsing this technology, realistic and clear 3D images can be displayed on holographic wires.
\nThis technology is used in advertising, cinema, computer games and virtual reality industries.
\nHolographic wires are examples of new technologies in the field of holography and photonics that allow us to produce three-dimensional images with high realism.<\/p>\n

Master Hologram is a type of holographic wire that is used as a reference for producing holographic copies.
\nIn the process of making holograms, a master wire is first prepared, which has the main pattern of optical interference.
\nThis master wire is then used to produce more copies of the hologram.
\nThe master wire is usually made by technologies such as photonics and optical interference.
\nIn the master wire manufacturing process, optical interference is recorded on a glass plate or holographic film.
\nThese optical interference patterns related to the desired holographic image are recorded on the master wire.
\nAfter the Master Sim is made, it is used to produce holographic copies.
\nUsing hologram etching techniques, the master wire’s optical interference patterns are copied onto other holographic wires.
\nThese wires can then be used to produce holographic images of any desired size and number.
\nIn general, the master sim is used as the master template for producing hologram copies.<\/p>\n
Electroforming and recombination are two key steps in the hologram production process.
\nThese two steps are respectively related to the preparation of the holographic matrix and the production of the hologram film as follows:<\/p>\n
Electroforming: In this step, the holographic matrix is \u200b\u200bprepared.
\nFirst, a holographic wire like the master wire (which we talked about) is taken as a template reference.
\nThis wire is precisely placed in an electrolytic solution and acts as a cathode.
\nThen a special anode is placed on the wire as a source of metal deposition.
\nThrough the alternating electric current, the metal ions are separated from the anode and accumulate on the wire as a deposit.
\nThis process creates a thin and precise layer of metal on the holographic wire, which is called the holographic matrix.
\nRecombination: In this step, using the holographic matrix prepared in the previous step, the hologram film is made.
\nThe holographic matrix is \u200b\u200bexposed to light simultaneously with a light-sensitive film (holographic film).
\nIn this process, light is simultaneously radiated from two directions to the holographic matrix and the hologram film.
\nThe optical interference patterns in the holographic matrix cause changes in the optical interference pattern of the recombination sensitive film.
\nThese changes record the optical interference pattern in the photosensitive film.
\nAfter the recombination process is completed, the resulting film is used as a hologram film.<\/p>\n
As a result, by using the electroforming step to prepare the holographic matrix and the recombination step to make the hologram film, we can produce holograms with high quality and high realism.
\nThis complex and specialized process requires special equipment and technologies that are performed by specialists in the fields of holography and photonics.<\/p>\n","protected":false},"excerpt":{"rendered":"
