Peter Gariaev and others have proposed a novel model of genetic “texts”. According to this model, DNA molecules serve as gene-sign continuum in any biosystem and form pre-images of biological structures as well as the entire organism as dynamical “wave copies” or matrixes that progress sequentially over time.
What is a hologram?
Holograms are three-dimensional images that appear suspended in midair, maintaining depth and parallax of objects they depict, making them excellent tools for communicating complex technical concepts or visually appealing products. Holograms also serve an entertaining purpose by giving audiences the sense that they’re present before an image.
Dennis Gabor invented holography in 1948. To record a hologram, an object must first be illuminated by laser light before being placed before an object sensor and illuminated; any light reflected off it strikes a piece of film known as a hologram negative with tightly packed and fine-detailed fringes that act like a diffraction grating, replicating exactly its interference pattern with real physical objects.
Once recorded, holograms can be seen through any viewing device – such as glasses – that displays them. When seen through such devices, their fringes will enable viewers to see an exact replica of whatever object was originally shown when moving or rotating in front of their view.
Holograms have long been used for 3D image display; now they can also transmit sound. This allows us to hear speakers’ voices more realistically; making this technology hugely popular within audiovisual industries as well as medicine or telepresence applications.
Holographic technology has also made it possible for people to communicate more naturally between one another than ever before, using a hologram to transmit the appearance and movements of another person, creating more natural conversations between people than would otherwise be the case. This has proven especially effective for business presentations where holograms offer engaging presentations that go beyond traditional slideshows.
Holograms offer another exciting application in mechanobiology. Gariaev has used holograms to create biomechanical models of chromosomes that allow researchers to better understand how they function within the body, as well as pinpoint any damaged sections or potential mutations to the genetic code. Holograms can even help detect damaged pieces and predict how they might impact genetic code mutation.
How does a hologram work?
Holograms are three-dimensional images created with laser devices and comprise virtual images produced from light reflecting from an object being holographed, combined with light from an equally collinear background where the recording takes place. Our brain interprets this interference pattern as a coherent three-dimensional image.
Holography depends on synchronizing its light source. Natural lighting tends to be incoherent, with bundles of particles coming and going out of phase – like traffic on a freeway – while laser light has all its photons passing through a given point at exactly the same time – creating clear interference patterns which can then be reconstructed as images.
Holograms offer another great advantage; they can be seen from any angle. By moving around a hologram of a chessboard for example, different perspectives of its image can be observed by moving the viewer. Pawns on either side of the king can also be observed.
At first, holograms were recorded onto photographic plates using laser light beams that passed over an object placed on it and directed by a beam of laser light; as it passed, dark stripes appeared depending on whether or not the light hit directly or was reflected off it; the resultant hologram could then be scanned using another laser scanner and reconstituting itself on screen.
Holograms can also be created digitally using digital signal processing, producing the interference patterns needed for reconstruction. This results in an image of exceptional quality which can be seen from all three dimensions without loss of resolution.
Holograms can also be created of moving objects, like an airplane in flight. While this method requires more sophisticated optics and processing techniques, it’s still possible to make one from an event happening quickly such as bullet travel down a barrel – using laser light recording wavefronts can then reconstructing them back into a hologram of bullet movement.
How can we create a hologram?
Holograms are a useful visual communication tool, being utilized in business presentations, medical diagnostics and even immersive entertainment. There are multiple methods for producing holograms but one of the most efficient approaches involves laser technology: this creates three-dimensional images with real parallax as well as recording multiple images simultaneously – especially beneficial in medical diagnostics, where this allows physicians to view complex body parts without endangering patient safety.
Optic holography was invented by Hungarian-British physicist Dennis Gabor in 1947 to improve image quality seen by his lab assistants. Since then, optical holography has become an integral component of audiovisual and security industries.
Holograms are made of layers of light that can be separated to reveal objects in their entirety, much like photographs are. Their production follows similar steps: first the object must be illuminated with laser light before placing it under a hologram plate to capture its image and take its photograph; the resulting hologram has all of the properties found in photographs such as spatial qualities and iridescent hues.
Holograms go beyond simply recording images; they also record information about an object’s movement, enabling it to be seen from any angle while still maintaining its depth and 3D appearance. Holograms allow viewers to observe objects moving too fast for traditional filming to capture, providing an alternative method of showing moving subjects that would otherwise be difficult or impossible. With numerous applications and projected future growth, this technology should become even more popular over time.
Holograms are created by illuminating an object with a coherent laser beam and then placing it over a holographic plate, which contains close-packed, finely detailed fringes which act like diffraction gratings to bend or diffract light into patterns that form waveforms that replicate an object and its movements. Multiple holograms may even be recorded on one plate at once and later displayed using different colours.
How can we use a hologram?
Science fiction fans may remember Princess Leia from Star Wars using holograms as science fact; but as technology develops, these futuristic projections have started making an appearance in our everyday lives – for instance doctors now using them to teach patients complex medical procedures, while entertainment companies experiment with lifelike images of performers created with holograms.
One of the fascinating aspects of holograms is their use for three-dimensional imaging of objects larger than their wavelength of recording light, providing a great way to magnify objects by 100X or even more! By creating a hologram of an object and then replaying it using visible light at an increased scale, a 100X magnification effect can be accomplished.
Holograms record both phase information and wave amplitude data simultaneously during recording; this gives them their three-dimensional character. Once reconstructed, these can either be seen by eye as virtual images, or photographed to create real photographs of an object.
Note that holograms only work when waves have the same frequency; most real-world light waves cannot create an effective hologram; however, researchers are currently developing techniques for creating coherent light sources capable of creating holograms.
C-LUT requires that each object point’s X-Y direction modulation factors are precomputed offline and stored in a table before being used online to calculate a hologram, which takes up most of calculation time and may introduce phase modulation errors that need to be addressed later. While this method requires more processing power for phase modulation errors correction and phase modulation errors must be corrected later, it provides a useful overview of basic hologram concepts – perhaps serving as the foundation of a school project! Furthermore, more advanced computer hologram calculations that use computer algorithms offer faster and more accurate calculations; these methods still rely on preprocessed modulation factors and require high performance GPU computer systems to achieve accuracy.
