The first hints of the existence of some kind of "image" appeared iran phone number library back in the 6th century, when the camera obscura was invented. This is an empty box with a millimeter hole through which light passes and hits the opposite wall in the form of an inverted image. A primitive, but at that time amazing and useful invention became the prototype of modern technologies, first cameras, and then televisions.
Beginning of research
To display an image on a screen, the device must receive it from somewhere. The first projection devices were invented back in the 1600s. To display, a simple system based on the same camera obscura or periscope was required, as well as an image source - for example, a lighting device and the object of the "shooting" itself. Such systems were mainly used in medicine to demonstrate various surgical processes to students. This happened in real time, but behind a wall.
However, the projector is only an optical device, which can be called an improved version of the ancient "shadow theater". And the television is not only optics, but also electronics. So, the founder of television and other technologies for transmitting information over a distance can be considered the Scottish scientist James Clerk Maxwell. In 1873, he proposed the theoretical foundations of electromagnetic waves, on which modern wireless transmission technologies were later built. However, he was not the one who invented the first television in the world.
The author of the concept of television is considered to be the German engineer Paul Nipkow, who in 1884 patented the "Nipkow disk" - a rotating plate with holes through which light passes, allowing the image to be laid out on lines. Each hole was equipped with a light-sensitive sensor that collected data and then transmitted it over wires in the form of electrical pulses. Later, they learned to use radio communication for
