Holographic screen from water

Today, Holographic Videos - the special effects that Hollywood uses in sci-fi movies are approaching reality.

The young Russian engineers from Astrakhan have created water screens with very clear images and even display flavors, making viewers feel like they are present at the scene of the event.

When activating this unusual screen, it seems at first that the image is formed from the air. But if you look closely, you can see that the image is made up of tiny droplets. More specifically from aerosols . But when I put my hand in front of the screen, my hand was not wet. There is also no water on the floor. All problems lie in the size of the water droplets. They are tiny, like tiny droplets of water that cause fog and clouds. In nature, they are formed due to the temperature difference, and here, the size of the necessary water particles is created with ultrasonic waves. Project developer "Misty screen" Maxim Kamanin said:

"We mix water particles of the desired size with a gentle aerodynamic flow. This is very important. What is received is that the screen evenly distributes micro particles".

The feature of aerodynamic equipment makes Russian design different from foreign devices.The Astrakhan scientists ' "fog screens" show images of integrity and stability when it comes into contact with objects, in other words, anything can be poked into the image, waving their hands on it. , but the image still retains its effect.

The principle of "fog screen" is quite simple. The image is projected on the aerosol screen. You can control the image by surfing your finger as usual with the touch screen of your tablet. Special camera with infrared sensor mounted in the device base, creating an aerosol screen according to the movement of the finger. Your computer can also handle up to 1500 finger touches with a delay of less than 0.2 seconds. Technical director of the project "Fog screen" Alexander Krasnotsvetov said:

'We use infrared cameras. When the finger touches the illuminated flow, the camera sees an infrared finger and recognizes them as a controller with the help of special software ".

Exhibitions, billboards and presentations. Currently, these are places where you can witness the application of Russian inventors' inventions. Certainly the number of users will increase more, if the image is added volume. It is possible to do that with a few water screens with special applications. Another nice feature of Russian technology is that it can be applied in everyday life. The interactive 'fog screen' with its eco-friendly material can also be used as an indoor humidifier.
