What is Helograph?

Helograph is a device used to send optical messages with the help of sunlight. Using heliography of some form or other date back to the ancient world, where numerous cultures reflected sunlight to send messages or signals at considerable distances. It was not until the age of 70. The Helographs were published by some militants so that people could maintain communication lines if other communication methods have decreased. Numerous human populations in history have seen it and used it in their favor. This principle was used in an organized manner in the 18th century, when several inventors developed helographers such as the Helograph of the MANCE, used in the Middle East in the 1970s and 80s. In order to be used, the object can be turned or closed to form a series of sweepers Světlakyé. These transmissions were commonly carried out in Morse code, which uses a number of long and short transmissions to transmit information. Helographs could also be established in reLé, while the reports were transmitted over long distances through a number of helographs.

Heliograph as a communication device there are a number of disadvantages. The first is that it is limited to daily use only in the lines of supervision, and if there is a cloud cover, it can disrupt the operation of the device. The transmission can also be captured by anyone who accidentally looks at viewing, which may require people to use the code. This in turn requires maintenance and updating codes so that enemies cannot break the code and read the captured messages.

, however, also has some advantages. It cannot be stuck, which allows people to communicate when the operating systems are resurrected. It is also not limited by power supply and functionality of the device; Even if the heliography is damaged, if the reflective part is intact, it will be possible to send messages with it.

Students who learn that Morse Code sometimes enjoys playing with helography as a means of communication. Is importantBe careful when exercising or demonstrating heliography, because the reflected light can damage the eyes if it is directed at them. It can also be dazzling for a moment, which is the main problem for drivers, pilots and other people who run motor vehicles. When using a heligar, people should take care of to make sure they know where the light always follows, and the device should be covered or closed if not used.
