With micro and nano cameras, invisibility is no longer a dream.
In short, the definition is that objects and things become invisible, imperceptible. Besides, invisibility is indeed a very interesting and wide-ranging subject. For many years, it has been able to revive people's curiosity. This concept has been used in many fields, such as science, technology, art, and popular culture, and has managed to become the subject of research and even films.
From a scientific point of view, the principle of invisibility works by either breaking light from an object or preventing it from reflecting light. In order to this image, the interaction between the object and light needs to be reduced. It uses optical technologies developed in recent years to direct light around an object, making it invisible. This can be achieved by means of devices operating within a certain range of electromagnetic spectrum. The known part of this range is the range of visible light that the human eye can perceive. Still, other electromagnetic ranges can also be used for invisibility. Radio waves, microwaves and infrared light can be used to make objects invisible. However, the technology of invisibility has not yet been fully developed and has some limitations. Invisibility technology can only operate in a certain electromagnetic spectrum, so it requires the use of a device that burns light in that spectrum to make an object invisible. Moreover, the invisibility technology only changes the direction of the light on the object. This does not cause the object to disappear completely, it only causes the image to change.
To explain in a more everyday language, it indicates that there is something missing in the environment where the objects are. This ensures that the location of the object cannot be detected due to a deficiency. In addition, the invisibility technology only affects the outer surface of the object. No changes are applied to the internal structure. This allows you to see the shadows of the object. Although light is reflected by bending, it shows that these objects cannot be made completely invisible within current technologies. It is much more complex and in-depth than we think it will take years to develop more practical applications.
Scientists and engineers continue to work on AR-GE on invisibility technology. Large strides will be made with the discovery of new materials and more sensitive devices on this technology, which is somewhat in parallel with nanotechnology.
Invisibility uses play a major role in military fields, in exploration and intelligence activities. It can make military vehicles and personnel invisible, making it difficult for the enemy to detect and target them. This technology can also be used in intelligence activities to escape enemy detection capabilities, such as spy satellites and intelligence devices. This reduces the enemy's ability to gather information during operations.
In the medical field, it could enable doctors to diagnose diseases using much thinner devices. To give an example, devices that are thin and flexible, such as endoscopic devices, use them to visualize organs in the body. Medical imaging tools, such as MRI, CT, and PET, also help diagnose patients by visualizing their internal organs, which can help make treatment more effective by making a more accurate diagnosis. With the advancement of technology, these devices can be improved to help patients experience less discomfort and better diagnosis. Finally, the clostrophobic effect that devices such as MRI devices have on some patients can be eliminated by making them invisible.
In the area of security, it can be used to make cameras more secret and effective. This technology allows civilian security personnel or police officers to perform their duties more effectively and safely with an invisible camera that can be placed on top of them. In particular, this technology can be used more secretly and effectively in camera systems. It can also be used in night vision devices and laser target indicators.
This technology, which is also used in the arts, entertainment and fashion worlds, could use invisibility technology to develop software for visual effects and animations. It helps to make the scenes in the movies more realistic and impressive. For the fashion world, it may also be possible to add a new dimension to the world of fashion by using the invisibility technology of the stage effect and the materials used in certain shows and clothes to make the models appear more impressively.
