- The maker offers a viewable range of 360 degrees.
- It is a user friendly maker and therefore don’t require any training for operation.
Materials needed for a 3D hologram manufacturers
A 3D hologram in most of the cases is made of two types of materials, one is heavy gauge and the other one is fine gauge. They differ from each other on the basis of the viewing distance and this viewing distance depends entirely on the thickness of the glass. Moreover, the two gauges also differ on the basis of their applications as heavy gauges serve the purpose of superior viewing distances whereas the fine gauge helps in viewing distances that are closer.
With markets being flooded with fake products and with government waking up to the piracy and counterfeits, the hologram business seems more of a profitable business. Probably it has become the first point of sale verification feature. As piracy regularly eats into the profits and reputation of big businesses, it has made several brand owners to sit up and take steps to protect their interests.
This hologram business or the popularity of holograms developed mainly because of brand identification and security. Mind you, each hologram is unique and one cannot recreate the same even with the same labor and machinery. This not only makes and excellent security proofs for bands but also assures consumers about the quality of the brand.
Hologram Types and its market share
Holograms symbolize brand identification and security. With and alarming rate of counterfeiting, the demand of holograms have increased manifold. Well to know about the hologram business firstly you need to access its types. Mainly there are three types of holograms. They are security, packaging and promotional.
- Security holograms have a great hold in the market. It is basically a low volume high margin business. Such holograms have a market size of Rs.150 crore.
- While packaging holograms has Rs. 250 Crore market and stands as a high volume low margin business. Here the price competition is greater in comparison to other.
- The promotional holograms are a popular phenomenon. Frankly speaking, there are hardly any makers of holograms and its market is reported to be less than Rs. 1 crore.
Well as not many companies are yet aware of the benefits of the holograms and as majority of the customers are still not aware of it, the market has still not grown to the size it could. Mainly the future of this company depends a lot on the acceptability of holograms. According to experts, this hologram business is meant for everyone who intends to start a holographic company but the main thing lies in careful technological up gradation and industry assessing. So, if you are thinking of entering this business, just go through the aforementioned guidelines and make you business a flourishing one.
White light hologram is somewhat different from regular holograms but you need to know the difference only after having an idea about the mechanism of a regular hologram. All you need to know about the functioning of a regular hologram is that two coherent beams are mainly needed for the production of a hologram and one of the beam is called the reference beam and the other one is called the object beam. As the two beams interfere, it gets recorded in the photographic film. And once the film is developed you can get a look of it by illuminating the developed film with a laser film.
Reflection hologram – A type of white light hologram
Regular holograms are therefore only capable of producing sharp images when viewed with a monochromatic light. However, reflection holograms are those which is capable of being viewed in a white light as well as in these type of white light hologram the object and reference beams actually stands on the opposite side of the photographic film. As a result, the plane of the film has the structure of the interference pattern lying perpendicular to it. You can have twenty or more layers within the emulsion, if the thickness is around 15 mm and it will ultimately result to a truly three dimensional recorded pattern. This developed film is illuminated with a white light beam which makes the hologram an automated selector of proper wavelength and that too for each angle of incidence. This ultimately makes a hologram, which you can view with white light from a point source.
Rainbow hologram involves a two stage process
The rainbow hologram is another type of white light hologram. Steven Benton Invented the hologram, which can be viewed even with the help of a transmitted light of an incandescent lamp. This hologram makes the phenomenon happen by a simple two stage process with the first step involving making of a transmission hologram. Then it involves construction of another hologram by treating the first image of the hologram as the object.
Hologram glasses are the new generation of improved 3D Glasses that serves a number of functions. It provides an experience that is much different from other reality glasses. Hologram glasses even have a variety of special images. However, the quality of the effects depends on the image as more simple image will provide a crisper and brighter effect.
Working of a hologram glass
The still picture that possesses a red composite image is the right component. The left component possesses a contrasting color, both of them are superposed, and the effect is seen when they are observed through the corresponding colored filters. Though the eyes are a few inches apart from each other yet, they correlate the picture. These correlating is helped by the brain and it is done even from different angles. Moreover, holographic glasses, which boasts a 3D effect makes the experience of watching 3D films truly worthy. The colored filters isolate the images with different colors and the images are only able to enter one eye at a time. However, when the images are projected by the brain, it is only one.
Advantages of hologram glasses
Hologram glasses also provide a lot of advantages and that is the prime reason for its increasing popularity. Some of the advantages that a hologram glass includes the fact that glasses are very efficient in correlating two images into one. It helps a lot in getting an overlook of the essence. Moreover, when you view through hologram images, you can’t differentiate between real and virtual images. This phenomenon often makes fantasy world look like real world. The particular technology is very much used in 3D or stereoscopic movies and last but not the least; it also allows the view with color.
Usage of hologram glasses
Hologram glasses have a widespread use. It is extensively used in various education fields as well as movie theaters. However, the biggest usage of hologram glasses are probably at Film production studios. For instance, Universal Studios consume a large chunk of hologram glasses’ usage. It is also used for proof of principle researches or various developments programmes.
Computer generated hologram are those kinds of holograms which gives the appearance of binary representation of interferogram. Here computers are used to scan, design, enhance and create images and patterns for developing 2D/ 3D holograms. Frankly speaking, this computer technology comes as a powerful technology for a wide range of display types including 2D, stereoscopic, volumetric and true 3D imaging.
How to make computer generated hologram
In order to make computer-generated hologram, first the image of the object is taken followed by the removal of the background of the image. The background of the image is removed adding white space around the object that helps in obtaining higher transmission. Remember the three basics elements in holography that includes light source, image and hologram plays a vital role. It is to be noted that if any two of these are known, then the third one can be easily calculated.
For instance if we know the diffraction pattern and the details of the double slit system, we could easily calculate the wavelength of the light. So, this is the basic idea behind the theory of computer generated hologram.
Uses of computer generated hologram
